LD5760EHigh Voltage Green-Mode PWM Controller with BNO Function
The LD5760E is a Green Mode PWM IC built-in with brown-in/ out functions in a SOP-7 or SOP-8 package. It minimizes the component counts, circuit space, and reduces the overall material cost for the power applications.
The LD5760E features HV start, green-mode power-saving operation, and internal slope compensation, soft-start functions to minimize the power loss and enhance the system performance.
With complete protection in it, as OLP (Over Load Protection), OVP (Over Voltage Protection), fast SCP (short circuit protection) and brown-in/out protection, LD5760E prevents the circuit from being damaged under abnormal conditions.
Furthermore, the LD5760E features frequency swapping and soft driving function to reduce the noise and improve EMI.
