STEVAL-USBPD27S

STEVAL-USBPD27S is a 27W AC-DC adapter reference design that works as USB power delivery provider with a single USB Type-C port supporting programmable power supply and featuring adaptive synchronous rectification. The reference design accepts a wide range of input voltage and delivers two well regulated fixed PDOs and two APDOs, finely adjusted to the advertised voltage range, thus managing the VCONN, as requested by the USB power delivery specification. The adapter meets the most stringent energy saving recommendations ensuring less than 40mW of no load power consumption. All PDOs are compliant with CoC ver. 5 – Tier 2 and DOE Level VI requirements except the 9VProg at 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 115VAC and 230VAC.
