LT8471 datasheet

Description

The LT8471 is a dual PWM DC/DC converter containing two internal 2A, 50V switches and an additional 500mA switch to facilitate step-down and inverting conversion.

Each 2A channel can be independently configured as a buck, boost, SEPIC, flyback or inverting converter. Capable ofgenerating positive and negative outputs from a single input rail, the LT8471 is ideal for many local power supply designs.

Features

1. Dual 2A and One 500mA, 50V Internal Power Switch Channels

2. 2A Primary Channels Can Be Buck, Boost, SEPIC, ZETA, Flyback or Inverting DC/DC Converter

3. 500mA Skyhook Channel Efficiently Generates Boosted Input Voltage

4. Wide Input Voltage Range of 2.6V to 50V

Description

The XL4016 is a 180 KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 8A load with high efficiency, low ripple and excellent line and load regulation. Requiring a minimum number of external components, the regulator is simple to use and include internal frequency compensation and a fixed-frequency oscillator. The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%. An over current protection function is built inside. When short protection function happens, the operation frequency will be reduced from 180KHz to 48KHz. An internal compensation block is built in to minimize external component count.
