LD7577B controller equivalent, high voltage green-mode pwm controller.
more protections like OLP (Over Load Protection), OVP (Over Voltage Protection), and brownout protection to prevent the circuit from being damaged under abnormal conditio.
z Switching AC/DC Adaptor and Battery Charger z Open Frame Switching Power Supply z LCD Monitor/TV Power
Typical Applic.
The LD7577B integrates several functions of protections, and EMI-improved solution in SOP-8/ DIP-8 package. It minimizes the component counts and the circuit space.
The device provides functions of low startup current, green-mode power-saving operati.
