LT1172HVCT#30PBF

Overview

The LT1172HVCT#30PBF is a monolithic high-power switching regulator from Analog Devices. It supports multiple standard topologies including buck, boost, flyback, forward, inverting, and Cuk configurations. The device integrates a high-current, high-efficiency internal switch along with complete oscillator, control, and protection circuitry. It operates with an input voltage range of 3 V to 60 V and provides an adjustable output voltage. The unit delivers up to 1.25 A output current at a fixed switching frequency of 100 kHz. It functions within a temperature range of -40°C to +100°C and utilizes a CT package.

Feature Summary

Supports versatile DC-DC conversion topologies including buck, boost, flyback, forward, inverting, and Cuk circuits.
Integrates a high-current, high-efficiency power switch on the die alongside all necessary oscillator and control logic.
Operates across a wide input voltage range suitable for various industrial power supply requirements.

Applications

Forward converter designs
Flyback converter implementations
Negative boost regulator circuits

Procurement Notes

Verify the specific suffix #30PBF against official Analog Devices documentation to confirm reel packaging specifications and tape-and-reel quantities. Ensure the component meets RoHS compliance standards required for your assembly process. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and lead times. Validate that the operating temperature range aligns with your system's thermal constraints.

Selection Notes

Select this component when a single IC must support multiple topology variations without external controller complexity. The integrated high-efficiency switch reduces external component count and board space. Consider the 1.25 A output capability and 100 kHz frequency for moderate power applications requiring flexible voltage conversion architectures.

Part Context

This part belongs to the LT1172 series of high-efficiency switching regulators. The series includes variants with different current ratings such as 5 A and 2.5 A options. These devices are designed for industrial and commercial applications requiring robust power management solutions with minimal external components.
