LT1170CQ#PBF

Overview

The LT1170CQ#PBF is a monolithic high-power switching regulator manufactured by Analog Devices Inc. It supports multiple standard topologies including buck, boost, flyback, forward, inverting, and Cuk configurations. The device features an integrated high-current switch with a maximum output current of 5 A. It operates within an input voltage range of 3 V to 60 V and provides an adjustable output voltage from 1.244 V to 40 V. The unit is housed in a 5-pin (5+Tab) TO-220 package and functions at a fixed switching frequency of 100 kHz.

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

Negative boost regulators
LCD contrast power supplies
Offline applications driving high-voltage FETs

Procurement Notes

Verify the specific suffix and manufacturer part number against official Analog Devices documentation to ensure compatibility. Confirm that the required topology and electrical parameters match the design specifications before integration. Check for any lead time variations or supply constraints directly with authorized distributors. Ensure the thermal management solution accommodates the TO-220 package requirements for the intended load conditions.

Selection Notes

Select this component when a single IC must support diverse DC-DC converter topologies such as buck, boost, or flyback. It is suitable for designs requiring up to 5 A output current and an input voltage range extending to 60 V. Consider the TO-220 package for applications where through-hole mounting or specific thermal dissipation characteristics are preferred over surface-mount alternatives.

Part Context

The LT1170 series represents a family of monolithic high-power switching regulators designed for versatility across various converter architectures. The LT1170CQ#PBF variant specifically utilizes the CQ temperature grade and the #PBF lead-free packaging designation. This model integrates the necessary control logic and power stage into a single chip, simplifying the design process for complex power supply systems compared to discrete solutions.
