36W: Universal Input: >90% Efficiency: Dual Output Aux Supply Ref Design for PSU
Description
TIDA-00709 is a 36-W dual-output auxiliary power supply with provision to accept both wide ranges of DC and AC inputs. Based on the input: this reference design can be used as an adapter or auxiliary power supply designed for use in power converters targeted for server: telecom and industrial system applications. This reference design is a quasi-resonant (QR) flyback converter implemented using UCC28740 constant voltage-constant current (CV-CC) flyback controller with optocoupled feedback for voltage and primary-side regulation (PSR) for current. For improved efficiency: TIDA-00709 uses synchronous rectification with sync controller UCC24636 and low RDS(on) MOSFET for main 12- V_ISO/2.75-A output. Hardware is designed and tested to pass conducted emissions: surge and EFT requirements. Additionally: the design has a built-in eFuse for multiple fault isolation for main output rail without affecting any other output.
Features
