High Voltage Multi-Mode PWM Controller with BNO Function
The LD5762E/A/H 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/H 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/H prevents the circuit from being damaged in abnormal conditions.
Furthermore, the LD5762E/A/H features frequency swapping and soft driving function to minimize the noise and improve EMI.
