LT1172CK

Overview

The LT1172CK is a monolithic high-power switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3 V to 60 V and provides an adjustable output voltage with a maximum output current of 1.25 A. The device features a fixed switching frequency of 100 kHz and a quiescent current of 6 mA. It supports multiple topologies including buck, boost, flyback, forward, inverting, and Cuk configurations. The component is housed in a SOIC-16 package and functions within a temperature range of 0°C to +100°C.

Feature Summary

Supports all standard switching configurations including buck, boost, flyback, forward, inverting, and Cuk topologies
Integrates a high-current, high-efficiency power switch on the die
Includes complete oscillator, control, and protection circuitry

Applications

Buck converter designs
Boost converter designs
Flyback converter designs
Forward converter designs
Inverting regulator circuits

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout compatibility and thermal characteristics. Ensure the selected variant matches the required operating temperature range and package style for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a versatile single-chip solution for various DC-DC conversion topologies is required. It is suitable for applications needing an input voltage up to 60 V and an output current of 1.25 A. Consider the SOIC-16 package constraints and thermal dissipation requirements for high-efficiency operation at the specified 100 kHz switching frequency.

Part Context

The LT1172 series comprises monolithic high-power switching regulators designed for flexibility across multiple converter architectures. This family integrates the power switch and control logic into a single chip, simplifying design implementation for buck, boost, flyback, forward, inverting, and Cuk converters while maintaining high efficiency.
