General Description

The LD5762E/A 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 reduce the overall material cost of

power applications.

The LD5762E/A 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.

With complete protection with it, like OVP (Over Voltage

Protection), OCP (Over Current protection) and

brown-in/out protection, LD5762E/A prevents the circuit

from being damaged in abnormal conditions.

Furthermore, the LD5762E/A features frequency

swapping and soft driving function to minimize the noise

and improve EMI.
