Description
The STEVAL-ISA193V1 evaluation board
implements a 15 W USB adapter with primary
sensing CC feature, based on the STCH02
current mode controller designed for offline
quasi-resonant flyback converters, capable of
providing constant output current (CC) regulation
using primary-sensing feedback.
The IC embeds a 650 V, non-dissipative, HV
startup cell, which, along with the extremely low
quiescent current and burst-mode management,
helps minimize residual input consumption, thus
achieving less than 10 mW under no-load
conditions.
The adapter is designed to meet the most
stringent energy saving recommendations
(EuCoC rev. 5 – Tier 2 and EPS of DOE USA) as
well as EN55022-Class-B Conducted noise
emissions.
The extremely small form factor and the output
USB connector makes this reference design
suitable for small USB chargers and adapters for
mobile phones, tablets and other hand held
equipment.
