General Description

The LD5762E1 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 LD5762E1 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), and

brown-in/out protection, LD5762E1 prevents the circuit

from being damaged in abnormal conditions.

Furthermore, the LD5762E1 features frequency

swapping and soft driving function to minimize the noise

and improve EMI.
