描述 Description

The LD5760 is a Green Mode PWM IC built-in with brown-in/ out functions in a SOP-7 or SOP-8 package. The device could therefore minimize the component counts, circuit space, and reduces the overall material cost of power applications.The LD5760 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 OLP (Over Load Protection), OVP (Over Voltage Protection), Fast SCP (short circuit protection) and Brown-in/out protection, LD5760 prevents the circuit from being damaged under abnormal conditions.Furthermore, the LD5760 features frequency swapping and soft driving function to minimize the noise and improve EMI.
