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.
