Overview
LD7922 08/02/2012 Primary-Side PWM Power Switch with CV/CC Operation VER.
00 General Description The LD7922 integrates a 700V power MOSFET and a primary-side feedback PWM controller with CV/CC operation in a DIP-7 package.
The LD7922 is designed for low power adapter/charger and LED lighting applications.
It minimizes the components counts and is available in tiny packages.
Those make it an ideal design for low cost applications.
The LD7922 provides constant voltage, constant current (CV/CC) operation requiring neither photo-coupler nor secondary control circuit.
Also, the LD7922 features OTP (Over Temperature Protection) and OVP (Over Voltage Protection) to prevent the circuit from being d...
