Description

The STEVAL-USBPD27S 27 W AC-DC adapter reference design works as USB

Power Delivery Provider with a single USB Type-C port supporting Programmable

Power Supply (PPS) and featuring adaptive synchronous rectification. Thanks to a

minimal bill of materials, it allows users to easily design compact and cost-effective

adapters.

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

specification.

The adapter meets the most stringent energy saving recommendations (EU CoC –

Tier 2 ver. 5 and DOE Level VI) ensuring < 40mW 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
