Analog Devices Inc.
The ADP7182 is a CMOS, low dropout (LDO) linear regulator that operates from −2.7 V to −28 V and provides up to −200 mA of output current. This high input voltage LDO is ideal for regulation of high performance analog and mixed signal circuits operating from −27 V down to −1.2 V rails. Using an advanced proprietary architecture, it provides high power supply rejection and low noise, and achieves excellent line and load transient response with a small 2.2 μF ceramic output capacitor.The ADP7182 is available in fixed output voltage and an adjustable version that allows the output voltage to range from −1.22 V to −VIN + VDO via an external feedback divider.The following fixed output voltages are available from stock: −5 V (3 mm × 3 mm LFCSP), −1.8 V, −2.5 V, −3 V, −5 V (TSOT), −1.2 V, −1.5 V, −2.5 V, −5 V (2.00 mm × 2.00 mm LFCSP). Additional voltages are available by special order.The ADP7182 regulator output noise is 18 μV rms independent of the output voltage. The enable logic is capable of interfacing with positive or negative logic levels for maximum flexibility. The ADP7182 is available in 5-lead TSOT, 6- and 8-lead LFCSP packages for a small, low profile footprint.Applications Regulation to noise sensitive applications Analog-to-digital converter (ADC) and digital-to-analog converter (DAC) circuits, precision amplifiers Communications and infrastructure Medical and healthcare Industrial and instrumentation

Analog Devices Inc.
The LTC2974 is a 4-channel Power System Manager used to sequence, trim (servo), margin, supervise, manage faults, provide telemetry and create fault logs. PMBus commands support power supply sequencing, precision point-of-load voltage adjustment and margining. DACs use a proprietary soft-connect algorithm to minimize supply disturbances. Supervisory functions include over and under current, voltage and temperature threshold limits for four power supply output channels as well as over and under voltage threshold limits for a single power supply input channel. Programmable fault responses can disable the power supplies with optional retry after a fault is detected. Faults that disable a power supply can automatically trigger black box EEPROM storage of fault status and associated telemetry. An internal 16-bit ADC monitors four output voltages, four output currents, four external temperatures, one input voltage and die temperature. Output power is also calculated. A programmable watchdog timer monitors microprocessor activity for a stalled condition and resets the microprocessor if necessary. A single wire bus synchronizes power supplies across multiple LTC Power System Management (PSM) devices. Configuration EEPROM with ECC supports autonomous operation without additional software.APPLICATIONS Computers and Network Servers Industrial Test and Measurement High Reliability Systems Medical Imaging Video

ADM1270ARQZ-R7
Analog Devices Inc.
The ADM1270 is a current-limiting controller that providesinrush current limiting and overcurrent protection for modularor battery-powered systems. When circuit boards are insertedinto a live backplane, discharged supply bypass capacitors drawlarge transient currents from the backplane power bus as theycharge. These transient currents can cause permanent damageto connector pins, as well as dips on the backplane supply thatcan reset other boards in the system.The ADM1270 is designed to control the inrush current, whenpowering on the system, via an external P-channel field effecttransistor (FET).To protect the system from a reverse polarity input supply, thereis a provision made to control an additional external P-channelFET. This feature prevents reverse current flow in case of a reversepolarity connection, which can damage the load or the ADM1270.The ADM1270 is available in a 3 mm × 3 mm, 16-lead LFCSP anda 16-lead QSOP.

ADM1278-1AACPZ-RL
Analog Devices Inc.
The ADM1278 is a hot swap controller that allows a circuit board to be removed from or inserted into a live backplane. It also features current, voltage, power, and temperature readback via an integrated 12-bit analog-to-digital converter (ADC), accessed using a PMBus™ interface. The load current is measured using an internal current sense amplifier that measures the voltage across a sense resistor in the power path via the HS+ and HS− pins. A default current limit of 20 mV is set, but this limit can be adjusted, if required.The ADM1278 limits the current through the sense resistor by controlling the gate voltage of an external N-channel FET in the power path, via the GATE pin. The sense voltage, and therefore the load current, is maintained below the preset maximum. The ADM1278 protects the external FET by limiting the time that the FET remains on while the current is at its maximum value.This current-limit time is set by the choice of capacitor connected to the TIMER pin. In addition, a constant power foldback scheme is used to control the power dissipation in the MOSFET during power-up and fault conditions. The level of this power, along with the TIMER regulation time, can be set to ensure that the MOSFET remains within safe operating area (SOA) limits.In case of a short-circuit event, a fast internal overcurrent detector responds within 320 ns and signals the gate to shut down. A 1500 mA pull-down device ensures a fast FET response.The ADM1278 features overvoltage (OV) and undervoltage (UV) protection, programmed using external resistor dividers on the UV and OV pins. A PWRGD signal can be used to detect when the output supply is valid, using the PWGIN pin to accurately monitor the output.The ADM1278 is available in a 32-lead LFCSP with a RETRY pin that can be configured for automatic retry or latch-off when an overcurrent fault occurs.Applications Servers Power monitoring and control/power budgeting Telecommunication and data communication equipment

ADP1052ACPZ-R7
Analog Devices Inc.
The ADP1052 is an advanced digital controller with a PMBus™ interface targeting high density, high efficiency, dc-to-dc power conversion. This controller implements voltage mode control with high speed, input line feedforward for enhanced transient and improved noise performance. The ADP1052 has six programmable pulse-width modulation (PWM) outputs capable of controlling most high efficiency power supply topologies, with added control of synchronous rectification (SR). The device includes adaptive dead time compensation to improve efficiency over the load range, and programmable light load mode operation, combined with low power consumption, to reduce system standby power losses.The ADP1052 implements several features to enable a robust system of parallel and redundant operation for customers that require high availability or parallel connection. The device provides synchronization, reverse current protection, prebias startup, accurate current sharing between power supplies, and conditional overvoltage techniques to identify and safely shut down an erroneous power supply in parallel operation mode.The ADP1052 is based on flexible state machine architecture and is programmed using an intuitive GUI. The easy to use interface reduces design cycle time and results in a robust, hardware coded system loaded into the built-in EEPROM. The small size (4 mm × 4 mm) LFCSP package makes the ADP1052 ideal for ultracompact, isolated dc-to-dc power module or embedded power designs.APPLICATIONS High density isolated dc-to-dc power supplies Intermediate bus converters High availability parallel power systems Server, storage, industrial, networking, and communications infrastructure
