Overview
The LT3752EFE#PBF is a current mode PWM controller optimized for active clamp forward converter topologies. It integrates a DC/DC housekeeping controller to power the main switching circuitry, eliminating the need for auxiliary windings or separate bias supplies. The device operates with an input voltage range of 4.5 V to 40 V and supports switching frequencies from 100 kHz to 500 kHz. It features a maximum duty cycle of 95% and includes shutdown functionality. Packaged in a 38-pin TSSOP with exposed pad, it supports operating temperatures from -40°C to +125°C.
Feature Summary
- Integrates a dedicated DC/DC housekeeping controller for internal bias generation
- Optimized for active clamp synchronous forward converter applications
- Supports wide input voltage ranges suitable for various industrial power systems
- Includes shutdown pin for system power management control
Applications
- Industrial power supply designs requiring isolated outputs
- Telecommunications equipment power architectures
- Active clamp forward converter implementations

Procurement Notes
Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm package marking matches LT3752EFE#PBF specifications. Check datasheet revisions for any design changes. Ensure storage conditions comply with moisture sensitivity levels. Validate supplier documentation against official Analog Devices part identification records before integration into production.
Selection Notes
Select this controller when designing active clamp forward converters requiring integrated bias regulation. Consider the 38-pin TSSOP-EP package for thermal performance. Evaluate the 100 kHz to 500 kHz frequency range against efficiency requirements. Verify compatibility with external MOSFETs and transformer designs. Assess thermal dissipation needs given the exposed pad package configuration.
Part Context
