Overview
The LT3753HFE#PBF is a current mode PWM controller optimized for active clamp forward converter topologies, supporting up to 100V input operation. It operates within a switching frequency range of 100 kHz to 500 kHz and features a 31-pin TSSOP EP package. The device includes an integrated house supply regulator providing 10 V output at 10 mA. It functions with a minimum operating temperature of -40°C and a maximum of +150°C, consuming 7.5 mA of working supply current.
Feature Summary
- Optimized for active clamp forward converter topology
- Supports high voltage input operation up to 100V
- Integrated house supply regulator for internal biasing
Applications
- High voltage DC-DC conversion systems
- Industrial power supplies
- Telecommunications equipment
Procurement Notes
Verify the specific suffix (#PBF) indicates lead-free compliance when sourcing. Confirm the 31-pin TSSOP EP package availability matches your PCB footprint requirements. Check official Analog Devices documentation for the latest product change notifications regarding manufacturing updates or pinout revisions before finalizing procurement plans.
Selection Notes
Select this component for designs requiring active clamp forward regulation with high input voltage tolerance. Ensure the thermal performance of the TSSOP EP package meets the application's heat dissipation needs. Verify that the 100 kHz to 500 kHz frequency range aligns with the desired transformer size and efficiency targets for the specific power level.
Part Context
This part belongs to the LT3753 series of current mode PWM controllers from Analog Devices. It is specifically engineered for applications demanding isolation capability and positive output configuration. The device serves as a core control element in efficient power conversion stages, distinct from general-purpose buck or boost controllers due to its specialized forward topology focus.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult Analog Devices directly for cross-reference recommendations if this specific variant is unavailable.
