The LT8601 is a triple channel, current mode, monolithic buck switching regulator with a programmable power-on reset. All regulators are synchronized to a single oscillator with an adjustable frequency from 250kHz to 2.2MHz. The LT8601 can be configured for micropower Burst Mode or Pulse-Skipping operation at light load. Micropower operation results in quiescent current of 30?A with all three regulators operating as shown in the application below with no load applied.The high voltage channels are synchronous buck regulators that operate from an input of 3.0V to 42V. The output currents are up to 1.5A (OUT1) and 2.5A (OUT2). The low voltage channel operates from an input of 2.6V to 5.5V. Internal synchronous power switches provide high efficiency with output currents up to 1.8A. The LT8601 uses a 2-phase clock with channel 1 operating 180? from channels 2 and 3 to reduce input ripple current on both HV and LV inputs. All channels have cycle-by-cycle current limit, providing protection against shorted outputs. Thermal shutdown provides additional protection.The LT8601 is available in a 40-lead 6mm ? 6mm QFN package.APPLICATIONS Automotive Systems Distributed Supply Regulation Industrial Controls and Power Supplies

The LTC2937 is a 6-channel power supply sequencer and voltage supervisor. Supplies are enabled or disabled with precise user controlled order and time spacing. To detect power supply output faults during sequencing and monitoring, the LTC2937 accurately monitors supply turn-on/-off delays and output voltage levels. In the event of a fault, response actions include complete power supply shutdown and optional restarts. Root cause of power faults are logged to EEPROM. For systems with high supply count, a simple single wire connection between multiple LTC2937 devices allows sequencing expansion to 300 supplies. After successful sequencing and supply voltage stabilization, the reset output pulls high to initiate microprocessor or other system activity. To accommodate supply margin testing, the reset output can be disabled. Upon supply turn-off, integrated current sources are available as needed to discharge slowly decaying supplies. Configuration EEPROM supports autonomous operation without software.Applications Network Servers Data Storage Systems Telecom Equipment High Availability Computer Systems

The LTC5586 is a direct conversion quadrature demodulator optimized for high linearity zero-IF and low-IF receiver applications in the 300MHz to 6GHz frequency range. The very wide IF bandwidth of more than 1GHz makes the LTC5586 particularly suited for demodulation of very wide-band signals, especially in Digital Pre-Distortion (DPD) applications. The outstanding dynamic range of the LTC5586 makes the device suitable for demanding infrastructure direct conversion applications. Proprietary technology inside the LTC5586 provides the capability to optimize OIP2 to 80dBm, and achieve image rejection better than 60dB. The DC offset control function allows nulling of the DC offset at the A/D converter input, thereby optimizing the dynamic range of true zero-IF receivers that use DC coupled IF signal paths. The wide-band RF and LO input ports make it possible to cover all the major wireless infrastructure frequency bands using a single device. The IF outputs of the LTC5586 are designed to interface directly with most common A/D converter input interfaces. The high OIP3 and high conversion gain of the device eliminate the need for additional amplifiers in the IF signal path.Applications 4G and 5G Base Station Receivers Wideband DPD Receivers Point-To-Point Broadband Radios High Linearity Direct Conversion I/Q Receivers Image Rejection Receivers

The LT1506 is a 500kHz monolithic buck mode switching regulator functionally identical to the LT1374 but optimized for lower input voltage applications. It will operate over a 4V to 15V input range compared with 5.5V to 25V for the LT1374. A 4.5A switch is included on the die along with all the necessary oscillator, control and logic circuitry. High switching frequency allows a considerable reduction in the size of external components. The topology is current mode for fast transient response and good loop stability. Both fixed output voltage and adjustable parts are available. A special high speed bipolar process and new design techniques achieve high efficiency at high switching frequency. Efficiency is maintained over a wide output current range by keeping quiescent supply current to 4mA and by utilizing a supply boost capacitor to saturate the power switch.The LT1506 fits into standard 7-pin DD and fused lead SO-8 packages. Full cycle-by-cycle short-circuit protection and thermal shutdown are provided. Standard surface mount external parts are used, including the inductor and capacitors. There is the optional function of shutdown or synchronization. A shutdown signal reduces supply current to 20?A. Synchronization allows an external logic level signal to increase the internal oscillator from 580kHz to 1MHz.Applications Portable Computers Battery-Powered Systems Battery Charger Distributed Power
