General Description
The LD5762K is a green mode PWM IC built-in with
brown-in/ out functions in a SOP-7 package. The device
could therefore minimize the component counts, circuit
space, and reduces the overall material cost of power
applications.
The LD5762K 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), brown-in/out protection and bulk cap.
OVP, LD5762K prevents the circuit from being damaged
in abnormal conditions.
Furthermore, the LD5762K features frequency swapping
and soft driving function to minimize the noise and
improve EMI.
