LD7921 switch equivalent, primary-side pwm power switch.
OTP (Over Temperature Protection) and OVP (Over Voltage Protection) to prevent the circuit from being damaged under abnormal conditions.
Features
z Built-in 700V Power M.
It minimizes the components counts and is available in tiny packages. Those make it an ideal design for low cost applic.
The LD7921 integrated a 700V power MOSFET and a primary-side feedback PWM controller with CV/CC operation in a SOP-6/DIP-7 package. The LD7921 is designed for low power adapter/charger and LED lighting applications. It minimizes the components counts.
