external MOSFET, can replace Schottky diodes in high-efficiency flyback converters.

  The MP6907 regulates the forward drop of an external switch to about 70mV, which

switches off once the voltage becomes negative.

  The MP6907 provides a SYNC interface to receive an external signal to shut down the

gate driver for reliable continuous conduction mode (CCM) operation. A programmable

light-load sleep mode can reduce the IC’squiescent current to ~150μA.

  The MP6907 is available in compact SOIC8

and TSOT23-6 packages.

 The MP6907 supports flyback converteroperation in continuous conduction mode

(CCM), discontinuous conduction mode (DCM), and quasi-resonant mode. The

control circuitry controls the gate in forward mode and turns the gate off when the MOSFET current is fairly low.

  VD ClampBecause VD can rise as high as 180V, a

high-voltage JFET is used at the input. To avoid excessive currents when VG drops

below -0.7V, a 1kΩ resistor is recommended between VD and the drain of the external MOSFET.

Under-Voltage Lockout (UVLO)

  When VDD is below the 4.2V UVLO threshold, the MP6907 enters sleep mode, and VG

remains at a low level.

Enable (EN) IV7GJ

  If EN is pulled low, the MP6907 is in shutdownmode, which consumes ~150μA of shutdown

current. If EN is pulled high during the rectification cycle, the gate driver will not start

until the next rectification cycle begins (see Figure 2)
