AN2300电容电源使用降压转换器的基础上VIPer12A的替代解决方案

AN2300
Application Note
An alternative solution to Capacitive power
supply using Buck converter based on VIPer12A

Introduction
In this paper three different power supplies with two outputs are introduced: a Capacitive
passive network, and two versions of a low cost SMPS Buck converter. The last two are
based on VIPer12A, a high voltage Power MOSFET with a dedicated current mode PWM
controller, start-up circuit and protection integrated on the same silicon chip by
STMicroelectronics.
