100V-450VDC: 5W: 80% Efficiency at 1W: Auxiliary Supply Reference Design for AC-DC Power Supplies
Texas Instruments
The TIDA-00708 is a 5-W multiple-output auxiliary power supply designed for use in power converters targeted for applications in industrial: server: telecom: and consumer systems. This reference design is a flyback converter implemented using the device UCC28881 that integrates the controller: 700-V power MOSFET: and internal current sense into one monolithic device. The design is simple: compact: and low cost due to minimal component count with all the necessary protections: such as output overcurrent: output short circuit: and over-temperature conditions: built in. Hardware is designed and tested to pass EFT requirements and meets low-power efficiency performance of Department of Energy (DoE) Level VI.
Features
- Designed for wide operating input voltage range from 100 VDC to 450 VDCVery low standby power of High efficiency >82% at 165 VDC and >84% at 400 VDC for loads greater than 75%Multiple outputs: 12 V/0.2 A: 3.3 V/0.25 A: 12 V/0.15 A (isolated)Ultra-simple circuit with low-cost off the shelf components with a compact form factor (32 mm x 25 mm)
