LT1172HVIQ#PBF

Overview

The LT1172HVIQ#PBF 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 from 1.244 V to 40 V. The device supports a maximum output current of 1.25 A, delivering up to 100 W of output power. It functions at a fixed switching frequency of 100 kHz and draws a quiescent current of 6 mA. The component is housed in a DDPAK-5 package and is rated for operation between -40°C and +100°C.

Feature Summary

Supports multiple standard switching topologies including buck, boost, flyback, forward, inverting, and Cuk configurations.
Integrates a high-current, high-efficiency internal switch along with complete oscillator, control, and protection circuitry on the die.

Applications

5V/1.25A Flyback Converter
-28V/1.25A Negative Boost Regulator

Procurement Notes

Verify the specific suffix and package type against the official datasheet to ensure compatibility with thermal requirements and pinout configurations. Confirm RoHS compliance status through manufacturer documentation prior to integration. Check for any recent Product Change Notifications (PCN) that may affect specifications or manufacturing locations.

Selection Notes

Select this component when a versatile single-chip solution is required for various DC-DC conversion topologies. It is suitable for designs needing high efficiency and integrated protection without external discrete switches. Consider the 1.25 A current limit and 100 kHz frequency when sizing passive components.

Part Context

This part belongs to the LT1172 series of high-power switching regulators. It shares functional similarities with the LT1171 but differs in output current capabilities. The series is designed for applications requiring flexible topology implementation within a compact surface-mount package.
