MengziIntegrated circuit management chip
Product Description
The SP6508F is a secondary synchronous rectifier chip used in isolated flyback power supply systems. It simulates the operation of a secondary Schottky rectifier diode and reduces losses with extremely low on-resistance. The SP6508F can operate in discontinuous conduction mode (DCM) and quasi-resonant mode (QR). Advanced blanking technology ensures stable and reliable operation of the chip in various operating modes.
The SP6508F detects the voltage drop across the on-resistance (Rds-on) of the built-in MOSFET to control the switching of the MOSFET. Simple peripheral applications
