描述 Description

The LD5760T is a PWM IC with built-in brown-in/out functions in a SOP-7/SOP-8 package which can minimize the component counts, circuit space, and reduce the overall material cost of power applications.

The LD5760T provides HV start, internal slope compensation and soft-start functions which can minimum the power loss and improve the system performance.

With the complete protection modes, like OLP (Over Load Protection), OVP (Over Voltage Protection), fast SCP(short circuit protection) and brown-in/out protection, this chip prevents the circuit from being damaged in abnormal conditions. 

Furthermore, the LD5760T features frequency trembling and soft driving function to minimize the noise and improve EMI.
