Fh6908a negative pole turn off synchronous rectification analog low voltage drop diode control IC chip tsot23-6 ultra low power rectifier 1W power consumption < 100ua static replacement mp6908

FS6908A Negative pole turn off synchronous rectification analog low voltage drop diode control IC chip TSOT23-6 Ultra low power rectifier  1w Power waste  <100uA static state   replace MP6908

FS6908A  It is an analog low voltage drop diode integrated circuit , Combined with an external switch , Replace Schottky diode in high efficiency flyback voltage converter .

The chip will be external synchronous rectifier (SR) MOSFET  The forward pressure drop is controlled at  40mV  about , Turn it off immediately when the voltage is negative .

At low output voltage, the battery shall be charged at  DCM  And false opening during quasi resonant operation . In use  FS6908A  It can generate power supply voltage for itself .

Programmable ring detection circuit , prevent  FS6908AFS6908A  To save space  TSOT23-6  encapsulation .​
