The LT3506 and the LT3506A are dual 1.6A step-down monolithic regulators that simplify the lives of system engineers. They eliminate the need for external power switches, thereby reducing solution size and BOM cost. Their outputs can be as low as 0.8V, satisfying the needs of the latest DSPs.

This document introduces a high voltage capacitor charger from Linear Technology Corporation. The charger operates in boundary mode and features high frequency and low power consumption.

This document introduces a space-saving triple-output regulator optimized for driving large TFT panel displays. The design is based on the LT3489 and provides 8V/600mA, 23V/10mA, and -8V/20mA outputs from a 3.3V input.

The LTC3835 is a low-power synchronous step-down controller that extends battery life in automotive applications. Its features include ultralow quiescent current (80µA), wide input voltage range (4V to 36V), constant frequency current-mode architecture, high-side inductor current sensing, adjustable soft-start, external clock synchronization, and CLKOUT pin.

The LTC2912, LTC2913, and LTC2914 supervisors respectively monitor single, dual, and quad power sup- plies for undervoltage and overvoltage with tight 1.5% threshold accuracy over temperature.

This document introduces the LTC3783 LED driver IC and its features and characteristics. The IC has full integration, high power, high accuracy, high efficiency and other characteristics.

The LT3837 is a flyback controller designed for 10W to 60W isolated applications. It offers high performance, simplicity, small size, and a minimum component count.

This article introduces a dual current-sense amplifier that simplifies H-bridge load monitoring design. This amplifier can directly monitor the load current without the need for a traditional small-value sense resistor. It can also handle the high-frequency interference caused by PWM techniques.

This document introduces the features of the LTC®3773 switching regulator. It is a 3-phase, triple output synchronous buck controller with built-in gate drivers, packaged in either a 5mm × 7mm QFN or a 36-pin SSOP. Its switching frequency can be set to 220kHz, 400kHz or 560kHz, or it can be synchronized to an external clock between 160kHz and 700kHz. The controller can step down from input voltages as high as 36V and the output voltage can be programmed from 0.6V to 5V.

This document introduces a simple and compact 4-output point-of-load DC/DC µModule system that meets the demanding size, performance, and power requirements of densely populated, high-performance systems. The LTM4601 DC/DC µModule converter shrinks the entire solution to the size of a low-profile IC, and its frequency synchronization and voltage tracking features allow for easy and quick configuration for multi-output applications.

The LTC3530 monolithic synchronous converter can be used to design a wide input voltage range buck-boost converter. This converter can output 3.3V from an input voltage of 1.8V to 5.5V, with an efficiency of up to 90%

The new LT®6000 family of 1µA and 13µA op amps operates on supplies as high as 16V all the way down to 1.8V, guaranteed over temperature.

This design note introduces the USB power manager with PowerPath Control, which offers the fastest charge time with the lowest heat.

This document introduces the LT3681 switch power supply chip, which integrates switch tube, Schottky diode and controller. The input voltage range is 3.6V-34V, supports 2A current, and has high efficiency. The switching frequency can be adjusted.
