Description

LT3837EFE#TRPBF Description
The LT3837EFE#TRPBF is an isolated switching regulator controller designed for medium-power flyback topologies. A typical application is 10W to 60W with the part powered from a DC supply. The LT3837EFE#TRPBF is a current mode controller that regulates an output voltage based on sensing the secondary voltage via a transformer winding during flyback. This allows for tight output regulation without the use of an optoisolator, improving dynamic response and reliability. Synchronous rectification increases converter efficiency and improves output cross-regulation in multiple output converters.

LT3837EFE#TRPBF Features
Senses Output Voltage Directly from Primary Side Winding—No Optoisolator Required Synchronous Driver for High Efficiency Supply Voltage Range 4.5V to 20V Accurate Regulation Without User Trims Programmable Switching Frequency from 50kHz to 250kHz Synchronizable Load Compensation Undervoltage Lockout Available in a Thermally Enhanced 16-Lead TSSOP Package
