ST VIPower VIPer22A-E Application Note

Introduction
In the past few years, many consumer products have been provided to the end user, such
as DVD or VCD players. Generally, their power supply requires multiple outputs to supply a
variety of control circuits: MCU, motor, amplifier, VFD.
Offline switch mode power supply regulators from ST's VIPer
avalanche rugged vertical power MOSFET with current mode control PWM circuitry. The
result is the innovative AC-DC converter, simpler, quicker, with reduced component count
and cheap.
The VIPer family complies with the "Blue Angel" and "Energy Star" norms, with very low total
power consumption in standby mode, thanks to the burst operation. This document presents
the application on DVD player power supply with the VIPer22A-E meeting the specifications
in Table 1.
