Overview
The LT3752MPFE-1 is a current mode PWM controller optimized for active clamp forward converter topologies. It integrates a DC/DC housekeeping controller to simplify system design. The device supports switching frequencies from 100 kHz to 500 kHz with a maximum duty cycle of 95%. It features a single output configuration capable of positive and isolation applications. The component operates within a junction temperature range of -55°C to 150°C and draws a typical operating supply current of 7.5 mA. It is housed in a TSSOP-38 package.
Feature Summary
- Optimized for active clamp forward converter topology
- Integrated DC/DC housekeeping controller
- Current mode PWM control architecture
Applications
- Active clamp forward power supplies
- DC/DC housekeeping circuits
- Industrial power management systems
Procurement Notes
Verify the specific suffix MPFE-1#PBF against the manufacturer's latest datasheet to confirm pinout compatibility and thermal specifications. Ensure the selected variant matches the required operating temperature range and package type for the target application environment.
Selection Notes
Select this component when designing active clamp forward converters requiring integrated housekeeping functionality. Consider the 100 kHz to 500 kHz frequency range and peak current mode operation for efficiency requirements. Verify that the TSSOP-38 package fits the PCB layout constraints.
Part Context
This part belongs to the LT3752 series, which includes variants like LT3752FE-1. The MPFE-1 designation indicates military-grade testing and performance guarantees over an extended temperature range compared to commercial equivalents.
Replacement Considerations
LT3752EFE-1#TRPBF and LT3752MPFE-1#TRPBF are available in tape-and-reel packaging. Verify if reel packaging is required instead of tube packaging for automated assembly processes.
