LD5762P中文资料通嘉科技数据手册PDF规格书

General Description

The LD5762P 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 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

prevents the circuit from being damaged in abnormal

conditions.

Furthermore, the LD5762P features frequency swapping

and soft driving function to minimize the noise and

improve EMI.
