This reference design replaces the now obsolete PMP5141 85-VAC to 265-VAC input 24-V/240-W output 90% efficient PFC + LLC reference design.
PMP22087
336-W Auxless AC/DC power supply reference design with 80 PLUS platinum compatible performance
PMP22087
Overview
This reference design is an AC/DC power supply design with critical conduction mode (CRM) PFC and half-bridge LLC series resonant converter that provides 24 V, 240-W continuous, 336-W peak output from a universal input AC voltage (90 VAC to 264 VAC). This design uses UCC28056 CRM/DCM PFC controller, UCC256404 enhanced LLC controller, and UCC24612-2 synchronous rectifier controller with burst mode enabled for low standby power losses. The design achieves 87 mW at 115 VAC and 124 mW at 230 VAC, and it also achieves 93.4% peak efficiency at 115-VAC input and 95.3% peak efficiency at 230-VAC input. The efficiency and power factor numbers also meet both 115-V and 230-V internal 80 PLUS Platinum specifications and DoE level VI requirements.
Features
- 24-V output with 240-W continue and 336-W peak output power capability
- 80 PLUS Platinum compatible performance
- Low, no-load power consumption without using additional auxiliary supply
- 93.4% peak efficiency at 115-VAC input and 95.3% peak efficiency at 230-VAC input
