LD5762E1
LD5762E1 is High Voltage Green-Mode PWM Controller manufactured by Leadtrend.
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 ponent 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 pensation, soft-start functions which could minimum the power loss and improve the system performance.
With plete 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.
