描述 Description

The LD5762P/Q is a green-mode PWM IC built-in with brown-in/ out functions in a SOP-7/SOP-8 package. The device could therefore minimize the component counts, circuit space, and reduces the overall material cost of power applications.

The LD5762P/Q features HV start, sleep-mode, green-mode power-saving operation, and internal slope compensation, soft-start functions which could minimum the power loss and improve the system performance.

With complete protection with it, like OPP (Over Power Protection), OVP (Over Voltage Protection), OCP (Over Current protection) and brown-in/out protection, LD5762P/Q prevents the circuit from being damaged in abnormal conditions. 

Furthermore, the LD5762P/Q features frequency swapping and soft driving function to minimize the noise and improve EMI.
