LD7750B controller equivalent, high voltage green-mode pwm controller.
more protections like OLP (Over Load Protection), OVP (Over Voltage Protection), and OTP (Over Temperature Protection) to prevent the circuit being damaged under abnormal.
The LD7750B integrates several functions of protections, and EMI-improved solution in a tiny package to minimize the component counts and the circuit space.
The device provides functions of low startup current, green-mode power-saving operation, lead.
