描述 Description

The LD5763A5/E5/H5 is a green mode PWM IC built-in with brown-in/ out functions in a SOP-8 package. It minimizes the component counts, circuit space, and reduces the overall material cost for the power applications.

The LD5763A5/E5/H5 features HV start, green-mode power-saving operation, and internal slope compensation, soft-start functions to minimize the power loss and enhance the system performance.

With complete protection in it, as OPP (Over Power Protection), OVP (Over Voltage Protection) and brown-in/out protection, LD5763A5/E5/H5 prevents the circuit from being damaged under abnormal conditions.

Furthermore, the LD5763A5/E5/H5 features frequency swapping and soft driving function to reduce the noise and improve EMI.
