Overview
The LT3752IFE-1#PBF is a current mode PWM controller optimized for active clamp forward converter topologies. It integrates a DC/DC housekeeping controller to simplify power supply design. The device operates within a switching frequency range of 100 kHz to 500 kHz and supports a maximum duty cycle of 95%. It features a single output configuration with a 10 V output voltage capability and 10 mA output current. The component functions reliably across an operating temperature range from -40°C to +125°C.
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 conversion systems requiring integrated housekeeping
- Industrial power management modules
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when sourcing. Confirm the -1 variant designation matches the required internal housekeeping controller integration. Ensure the TSSOP-38 package footprint aligns with PCB layout requirements. Check manufacturer documentation for any product change notifications affecting pinout or electrical characteristics prior to final procurement.
Selection Notes
Select this component when designing active clamp forward converters requiring integrated auxiliary power generation. The current mode control offers robust transient response. Consider the 100 kHz to 500 kHz frequency range for inductor sizing. Verify thermal performance within the -40°C to +125°C range for the target application environment. Ensure compatibility with external MOSFET drivers for the synchronous rectification scheme.
Part Context
This part belongs to the LT3752 series, which includes variants like LT3752IFE and LT3752IFE#WPBF. The series focuses on high-performance switching controllers for advanced forward converter applications. The LT3752IFE-1#PBF specifically denotes the lead-free, tube-packaged version with integrated housekeeping capabilities, distinguishing it from tape-and-reel or non-integrated variants.
Replacement Considerations
LT3752IFE#PBF serves as a direct functional substitute within the same family, differing primarily in packaging or suffix variations rather than core topology.
