LD5760H数据手册Leadtrend中文资料规格书

描述 Description

The LD5760H is a Green Mode PWM IC built-in with brown-in function 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 LD5760H 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 protection, LD5760H prevents the circuit from being damaged under abnormal conditions. 

Furthermore, the LD5760H features frequency swapping and soft driving function to reduce the noise and improve EMI.
