Product Introduction

LT1941EFE Three-channel, monolithic switching regulator

peculiarity

Wide input range: 3.5V to 25V
3 switching regulators with internal power switches: 3A buck type, 2A buck type, and 1.5A negative output/boost type
The inverting switch operation reduces ripple
Independent shutdown/soft start pins
The independent power good indicator simplifies power sequencing
The input voltage power good indicator monitors the input power supply
Small inductors and ceramic capacitors are used
The frequency is a constant switching frequency of 1.1MHz
Thermally enhanced 28-pin TSSOP package

Typical applications:

description

® The LT 1941 is a switched three-channel, current-mode DC/DC converter with an internal power supply, and the two regulators are buck-type converters with 3A and 2A power supplies. The third regulator can be configured as a boost, load; output or SEPIC-type converter with a 1.5A power switch, and all three converters are synchronized to a frequency of 1.1MHz DSP connection.

wide input from 3.5V to 25V; With a voltage differential range, the LT1941 can regulate a wide range of power supplies, from 4-cell and 5V logic power supply rails to untuned wall transformers, lead-acid batteries and distributed power supplies.
