PR779 A 1.2kW Universal Input Interleaved CCM PFC Power Board | TI.com
PR779: The PR779 is a 1.2 kW universal input (85 to 270 VRMS) interleaved PFC converter with 390 VDC output. It achieves efficiencies greater than 95% at 115 Vac from 20% to 100% load. Efficiency is greater than 97% for the same load group when input is 230 Vac. Power factor is greater than 0.98 for the same load range and either 115 VAC or 230 VAC input. The design meets current EN61000-3-2 requirements. The design consists of two boards. The main board, PR779, includes the power train components and a daughter board, PR780. The daughter board contains all the necessary control circuitry to drive the power train. The control is based on the UCC28070 continuous current mode interleaved PFC controller.
SEPIC, Sync Buck (3.3V @ 5A) for Radios
PMP2332.2: There are two supplies on PMP2332 and it has two outputs of 24V and 3.3V. The first supply is a SEPIC that converts the wide input voltage range of 6 to 40 volts to 24 volts. The second supply converts the 24 volts to 3.3 volts.
SEPIC, Sync Buck (24V @ 1.5A) for Radios
PMP2332.1: There are two supplies on PMP2332 and it has two outputs of 24V and 3.3V. The first supply is a SEPIC that converts the wide input voltage range of 6 to 40 volts to 24 volts. The second supply converts the 24 volts to 3.3 volts.
PMP5568 A Fully Featured, 350W Offline High Performance Power Supply | TI.com
PMP5568: This project is a complete 350W, high performance, high speed offline power supply solution. It contains a novel, microcontroller-driven synchronous bridge rectifier, a 2-phase interleaved PFC stage and a phase-shifted fullbridge as down converter. It has an universal input (85 .. 265V AC) and the output voltage is adjustable between 12 and 14V. The continuous output current is 25A, the peak current is 27A. A second microcontroller monitors several values (input voltage, PFC voltage, output voltage, output current, temperatures), is the interface to the user (LCD, push-buttons), adjusts the output voltage and synchronizes the switching frequency of all converters.
