先进的电压模式脉冲宽度调制器 Advanced Voltage Mode Pulse Width Modulator
DESCRIPON
The UCC35701/UCC35702 family of pulse width modulators is intended for isolated switching power supplies using primary side control. They can be used for both off-line applications and DC/DC converter designs such as in a distributed power system architecture or as a telecom power source. The devices feature low startup current, allowing for efficient off-line start ing, yet have sufficient output drive to switch power MOSFETs in excess of 500kHz.
