DC463A: Demo Board for LTC3700 Constant Frequency Step-Down DC/DC Controller with LDO Regulator.

The LT3430/LT3430-1 are monolithic buck switching regulators that accept input voltages up to 60V. A high efficiency 3A, 0.1? switch is included on the die along with all the necessary oscillator, control and logic circuitry. A current mode architecture provides fast transient response and excellent loop stability.Special design techniques and a new high voltage process achieve high efficiency over a wide input range. Efficiency is maintained over a wide output current range by using the output to bias the circuitry and by utilizing a supply boost capacitor to saturate the power switch. Patented circuitry* maintains peak switch current over the full duty cycle range. A shutdown pin reduces supply current to 30?A and a SYNC pin can be externally synchronized with a logic level input from 228kHz to 700kHz for the LT3430 or from 125kHz to 250kHz for the LT3430-1.The LT3430/LT3430-1 are available in a thermally enhanced 16-pin TSSOP package.Applications Industrial and Automotive Power Supplies Portable Computers Battery Chargers Distributed Power Systems

Demonstration circuit 1379B is a step-down DC/DC switching regulator featuring the LTM8025 μModule® regulator. The demo board is designed to deliver a 3.3V @ 3A output from a 5.5V to 36V input. The wide input range of the LTM8025 allows a variety of input sources such as automotive batteries, wall adaptors and industrial supplies. The modes of operation (Burst Mode® operation or synchronization) are jumper-selectable. Burst Mode operation improves efficiency at light loads. The LTM8025 can be synchronized over a 250kHz to 2MHz range.

Demonstration circuit 1392A features the LTM4604AEV, the high efficiency, high density switch mode step-down μModule® regulator. The input voltage range is from 2.375V to 5.5V with a jumper selectable output voltage from 0.8V to 3.3V. The rated load current is 4A, while derating is necessary for certain VIN, VOUT and thermal conditions. By using the TRACK pin, the output can be set to coincidentally or ratiometrically track to another voltage rail.

The LT3011 is a high voltage, micropower, low dropout linear regulator. The device is capable of supplying 50mA of output current with a dropout voltage of 300mV. Designed for use in battery-powered high voltage systems, the low quiescent current (46?A operating and 1?A in shutdown) is well controlled in dropout, making the LT3011 an ideal choice.The LT3011 includes a PWRGD flag to indicate output regulation. The delay between regulated output level and flag indication is programmable with a single capacitor. The LT3011 also has the ability to operate with very small output capacitors; it is stable with only 1?F on the output. Small ceramic capacitors can be used without the addition of any series resistance (ESR) as is common with other regulators. Internal protection circuitry includes reverse battery protection, current limiting, thermal limiting, and reverse current protection.The LT3011 features an adjustable output with a 1.24V reference voltage. The device is available in the thermally enhanced 12-lead MSOP and the low profile (0.75mm) 10-pin (3mm ? 3mm) DFN package, both providing excellent thermal characteristics.Applications Low Current High Voltage Regulators Regulator for Battery-Powered Systems Telecom Applications Automotive Applications

The LT3029 is a dual, micropower, low noise, low dropout linear regulator. The device operates either with a common input supply or independent input supplies for each channel, over an input voltage range of 1.8V to 20V. Each output supplies up to 500mA of output current with a typical dropout voltage of 300mV. Quiescent current is well controlled in dropout. With an external 10nF bypass capacitor, output noise is only 20?VRMS over a 10Hz to 100kHz bandwidth. Designed for use in battery-powered systems, the low 55?A quiescent current per channel makes it an ideal choice. In shutdown, quiescent current drops to less than 1?A. Shutdown control is independent for each channel, allowing for flexible power management.The LT3029 optimizes stability and transient response with low ESR ceramic output capacitors, requiring a minimum of only 3.3?F. The regulator does not require the addition of ESR, as is common with other regulators.Internal circuitry provides reverse-battery protection, reverse-current protection, current limiting with foldback and thermal shutdown. The device is available as an adjustable output voltage device with a 1.215V reference voltage. The LT3029 is offered in the thermally enhanced 16-lead MSOP and 16-lead, low profile (4mm ? 3mm ? 0.75mm) DFN packages.Applications General Purpose Linear Regulator Battery-Powered Systems Microprocessor Core/Logic Supplies Post Regulator for Switching Supplies Tracking/Sequencing Power Supplies
