LT1176-5 Datasheet Step-down Switching Regulator

Manufacturer: Linear Technology (now Analog Devices)

Overview: LT1176/LT1176-5 Step-Down Switching Regulator.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The LT®1176 is a 1A monolithic bipolar switching regulator which requires only a few external parts for normal operation.

The power switch, all oscillator and control circuitry and all current limit ponents are included on the chip.

The topology is a classic positive buck configuration but several design innovations allows this device to be used as a positive-to-negative converter, a negative boost converter, and as a flyback converter.
