The MK1620 is a dual channel synchronous rectifier (SR) controller IC for high performance system. With the ultra-low quiescent current, appropriate gate drive method and independent sampling input, the MK1620 can achieve maximum efficiency under any load.

The MK1620 operates over a wide supply voltage range from 4.6V to 36V, making it With dual-channel drivers and independent differential sampling, it is easy to design and use.

The extremely low 10ns turn−off propagation delay time and high sink current (~2.5A) capability of the driver improve SR VDS stress.

The unique VG clamping circuit works well to prevent VG from turning on by fast rising at VD pin with no VCC, that avoids the shoot through between primary side and secondary side during system startup even if the SR VCC is still below 2V.

MK1620 has appropriate logical protection features, internal logic interlock and two-channels interlock time can make the system more reliable.
