LT1172HVCQ#TRPBF

Overview

The LT1172HVCQ#TRPBF is a monolithic high-power switching regulator from Analog Devices. It integrates a high-current, high-efficiency switch with all necessary oscillator, control, and protection circuitry on the die. The device supports a wide input voltage range of 3V to 60V and delivers an output current of 1.25A. Operating at a fixed switching frequency of 100kHz, it achieves up to 100W of output power. It functions in standard topologies including buck, boost, flyback, forward, inverting, and Cuk configurations.

Feature Summary

Integrates a high-current, high-efficiency power switch with complete oscillator and control circuitry
Supports multiple standard switching configurations including buck, boost, flyback, forward, inverting, and Cuk
Operates within a wide input voltage range of 3V to 60V

Applications

Buck converter circuits
Boost converter circuits
Flyback converter designs
Forward converter applications
Inverting and Cuk topology implementations

Procurement Notes

Verify the specific suffix HVCQ against official Analog Devices documentation to confirm temperature grade and package type. Confirm the TRPBF designation indicates tape-and-reel packaging. Ensure compatibility with required operating temperatures and verify RoHS compliance status through the manufacturer's latest datasheet before procurement.

Selection Notes

Select this component for applications requiring a versatile single-chip solution for various DC-DC conversion topologies. The integrated switch simplifies design by eliminating external power transistors. Consider the 100kHz switching frequency for balancing efficiency and passive component size. Verify that the 1.25A output current meets load requirements across the specified 3V to 60V input range.

Part Context

The LT1172 series comprises monolithic high-efficiency switching regulators available in various current ratings. This model represents the 1.25A variant within the family. It shares core architecture with higher current versions like the LT1170 and LT1171, offering flexibility in industrial and commercial power supply designs requiring robust regulation.
