PMP6570: The PMP6570 reference design uses the UCC28050 transition mode PFC controller to generate an isolated 5V/2A output from a universal 90VAC to 300VAC input. This design combines both power factor correction and output regulation in a single stage. In addition, the UCC24610 is used to control a synchronous rectifier on the secondary side of the isolation boundry, improving efficiency.
TIDA-00127: This power supply solution for Protection Relays handles an ultra-wide range of both AC (88-276V AC) and DC (24-250V DC) inputs making it a suitable platform to power a variety of Protection Relays. The power supply is designed to output industry standard voltages (such as +/- 12V and isolated 6.75V) required in many Protection Relays while also providing excellent line and load regulation (< +/- 3%). This solution has been engineered for high wattage (30W) with good efficiency (up to 78%) and has also been pre-compliance tested for IEC61000-4 (EFT and Surge) and CISPR 11 Class A (Interference).
