General Description
The LD5760 is a Green Mode PWM IC built-in with brown-in/ out functions in a SOP-7 or SOP-8 package. The device could therefore minimize the component counts, circuit space, and reduces the overall material cost of power applications.
The LD5760 features HV start, green-mode power-saving operation, and internal slope compensation, Soft-start functions which could minimum the power loss and improve the system performance.
