STEVAL-ISA193V1

Оценочная плата, USB адаптер STCH02 CC с чувствительностью первичной стороны, 15Вт, 5В- 3А выход.

The STEVAL-ISA193V1 from STMicroelectronics is an evaluation board implements a 15W USB adapter with primary sensing CC feature. It is 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 650V, non-dissipative, HV start-up cell which along with the extremely low quiescent current and burst-mode management, helps minimize residual input consumption, thus achieving less than 10mW under no-load conditions. The adapter is designed to meet the most stringent energy saving recommendations 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.
