LT1952IGN-1#PBF

Overview

The LT1952IGN-1#PBF is a single-switch synchronous forward converter controller manufactured by Analog Devices Inc. It operates within an input voltage range of 6.82V to 25V and supports switching frequencies from 100kHz to 500kHz. The device features a maximum duty cycle of 90% and draws a supply current of 5.2mA. Designed for surface-mount applications, it is housed in a 16-pin SSOP package with a tube packaging format. The component functions as a positive isolation-capable DC-DC controller optimized for current mode PWM control.

Feature Summary

Optimized for current mode PWM control using a single primary MOSFET in forward converter topologies
Supports synchronous rectification for improved efficiency in isolated power designs
Capable of operating with adjustable output voltages suitable for step-up or step-down configurations

Applications

Isolated DC/DC converter designs requiring single-switch topology
Power supplies utilizing forward converter architectures
Applications needing synchronous rectification for enhanced performance

Procurement Notes

Verify the specific suffix #PBF against official Analog Devices documentation to confirm lead-free compliance and RoHS status. Confirm that the SSOP-16 package matches your PCB footprint requirements. Check for any obsolescence notices or lifecycle changes directly from the manufacturer, as distribution availability may vary across regions.

Selection Notes

Select this component when designing isolated power systems based on the forward converter topology. Ensure the required switching frequency falls within the 100kHz to 500kHz operational range. Verify that the input voltage supply stays within the 6.82V to 25V limit. Consider the thermal characteristics of the SSOP-16 package for your specific heat dissipation needs.

Part Context

This part belongs to the LT1952 series of switching controllers designed for high-efficiency power conversion. It serves as a core control element for forward converters, distinguishing itself through synchronous rectification capabilities. The series is intended for applications demanding reliable isolated power delivery with precise current mode regulation.
