LD5763P3数据手册Leadtrend中文资料规格书

描述 Description

The LD5763P3 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 LD5763P3 features HV start, green-mode power-saving operation, peak load mode for heavy load condition 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), fast OSCP (Output Short Circuit Protection) and brown-in/out protection, LD5763P3 prevents the circuit from being damaged under abnormal conditions.

Furthermore, the LD5763P3 features frequency swapping and soft driving function to reduce the noise and improve EMI.
