LT1268BCQ#PBF

Overview

The LT1268BCQ#PBF is a switching voltage regulator IC from Analog Devices, housed in a DDPAK-5 (TO-263-6) surface-mount package. It supports Boost, Buck, and Flyback topologies with an adjustable output voltage ranging from 1.244V to 60V. The device handles a switch current of 7.5A and operates within an input voltage range of 3.5V to 30V. It functions at a fixed switching frequency of 150kHz and includes shutdown capability. The component is rated for junction temperatures between 0°C and +125°C.

Feature Summary

Supports multiple converter topologies including boost, buck, and flyback configurations
Capable of delivering high switch current for demanding power applications
Features adjustable output voltage control for flexible system design

Applications

Industrial power supply systems requiring versatile topology support
Battery-powered equipment utilizing boost or buck conversion stages
Embedded systems needing isolated flyback power generation

Procurement Notes

Verify the specific suffix and package variant against the official datasheet to ensure compatibility with thermal management requirements. Confirm that the operating temperature range aligns with the intended environmental conditions. Cross-reference the pinout diagram with the target PCB layout to prevent installation errors during assembly.

Selection Notes

Select this component when a single IC must support multiple DC-DC converter architectures without changing parts. Ensure the external inductor and capacitor selections are rated for the 7.5A switch current limit. Verify that the input voltage source remains stable within the specified 3.5V to 30V window to maintain regulation integrity.
