STEVAL-SMACH15V1数据手册开发板套件编程器的评估板-DC/DC与AC/DC（离线）SMPS规格书PDF

描述 Description

The STEVAL-SMACH15V1 USB adapter evaluation board is based on the STCH03 offline PWM controller for low standby adapters. The controller can provide constant output current (CC) regulation using primary sensing feedback.The device combines a high-performance low-voltage PWM controller chip and a 650 V HV start-up cell in the same package. It also features extremely low quiescent current and burst-mode management. These features help minimize residual input consumption to less than 15 mW under no-load conditions.The device offers output overvoltage protection (OVP) and over-temperature protection (OTP). It also offers Hiccup-mode protection for when the transformer saturates or the secondary diode fails short, and an output UVP protection that limits the average output current when an output short circuit occurs.The adapter satisfies energy saving recommendations (EuCoC rev. 5 – Tier 2 and EPS of DOE USA) and EN55022-Class-B Conducted noise emissions.The small form factor and the output USB connector renders the design suitable for small USB chargers and adapters for mobile phones, tablets and other handheld equipment.
