Overview
The LT3752HFE-1#WPBF is a current mode PWM controller optimized for active clamp forward converter topologies. It integrates a DC/DC housekeeping controller to supply power to the primary side circuitry, eliminating the need for auxiliary windings. The device operates within a switching frequency range of 100 kHz to 500 kHz and supports a single output configuration. It functions with an input voltage up to 40 V and includes shutdown capabilities. The component is housed in a TSSOP-38 package and is rated for operation between -40°C and +150°C.
Feature Summary
- Integrates a dedicated DC/DC housekeeping controller to eliminate auxiliary winding requirements
- Optimized for active clamp forward converter topology with current mode control
- Supports wide input voltage ranges suitable for various industrial applications
Applications
- Industrial power supplies
- Telecommunications equipment
- Data center power distribution
Procurement Notes
Verify the specific suffix designation against official Analog Devices documentation to confirm pinout compatibility and thermal characteristics. Ensure that the selected variant matches the required operating temperature range and packaging constraints for your specific design implementation.
Selection Notes
Select this component when designing active clamp forward converters requiring integrated housekeeping power. Consider the TSSOP-38 package size and thermal performance relative to your board layout. Verify that the internal housekeeping regulator meets the quiescent current requirements of your primary side logic.
Part Context
This part belongs to the LT3752 series of synchronous forward controllers. It is designed to simplify high-efficiency power supply designs by combining main control and housekeeping functions into a single IC, reducing component count and improving reliability compared to discrete solutions.
Replacement Considerations
Consult official substitution guides for equivalent parts from Analog Devices or other manufacturers. Verify electrical parameters and pin compatibility before replacing.
