Overview
The LT3752EFE#TRPBF is a switching controller IC designed for active clamp synchronous forward converters. It integrates a DC/DC housekeeping controller and supports isolation-capable outputs. The device operates within a frequency range of 100 kHz to 500 kHz and features a single output configuration. It functions with a maximum output voltage of 10 V and an output current capability of 10 mA. The component operates reliably across a temperature range from -40°C to +125°C, consuming a typical operating supply current of 7.5 mA.
Feature Summary
- Optimized for active clamp forward converter topology
- Integrated DC/DC housekeeping controller
- Supports isolation-capable output configurations
Applications
- Active clamp forward power supplies
- Isolated DC-DC conversion systems
- Industrial power management modules
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the manufacturer designation matches Analog Devices Inc. to ensure authenticity. Check regional availability restrictions as some distributors may limit sales in certain areas. Ensure the package type corresponds to the required 38-TSSOP-EP footprint for proper board integration.
Selection Notes
Select this controller when designing active clamp forward topologies requiring integrated housekeeping power. The wide operating temperature range suits industrial environments. Consider the 100 kHz to 500 kHz frequency range for inductor sizing. Verify compatibility with external switch ratings against the 10 V output specification.
Part Context
This component belongs to the LT3752 series, which includes variants like the LT3752-1. These controllers are specialized for high-efficiency forward converter applications. The series emphasizes simplified design through integrated housekeeping functions. The LT3752EFE#TRPBF represents the tape-and-reel version of the standard LT3752EFE part.
Replacement Considerations
LT3752EFE#PBF serves as the tube-packaged equivalent. LT3752EFE-1#TRPBF offers similar functionality with potential pinout or feature variations. LT3752FE Marking parts correspond to the same internal silicon. Verify pin compatibility before substitution.
