LD7765 Description
The LD7765 is a Green Mode PWM IC, featuring X-cap discharge functions to reduce the discharge resistor loss in less ponent counts. The LD7765 provides HV start-up, green-mode power-saving operation, internal slope pensation and Soft-start functions which could minimize the power loss and enhance the system performance. With plete protection as OLP/ OVP/ OTP and brown-in/out, this chip prevents the circuit from...
