STMicroelectronics Compact 27W USB Type-C Power Delivery 3.1 with PPS adapter reference design Power Management for

The reference design accepts a wide range of input voltage and delivers two well regulated fixed PDOs (5V@5A, 9V@3A) and two APDOs (5VProg@5A and 9VProg@3A), finely adjusted to the advertised voltage range (Programmable Power Supply or PPS), thus managing the VCONN, as requested by the USB Power Delivery specification.

The adapter meets the most stringent energy saving recommendations (EU CoC – Tier 2 ver. 5 and DOE Level VI) ensuring < 40 mW of no load power consumption. All PDOs are compliant with CoC ver. 5 – Tier 2 and DOE Level VI requirements except the 9VProg@3A APDO, guaranteeing the compliance with the minimum four-point average efficiency in active mode.

The system has been tested to verify conducted noise emissions and compliance with the EN55022 (Class B) using standard average detectors, at half and full load with input voltage of 115 VAC and 230 VAC.
