MOSFET controller
2 May 2012, Power Electronics / Power Management

Enabling flyback power supply designers to replace inefficient Schottky rectifiers with a MOSFET driven as an ideal diode, the ZXGD3105N8 synchronous MOSFET controller from Diodes Incorporated can achieve a standby power consumption for set-top boxes of less than 100 mW and full-load efficiencies greater than 87%.

Drawing a quiescent current of less than 1 mA, and with its ability to operate from supply voltages as low as 4,5 V, the controller delivers flyback power supplies capable of exceeding the Energy Star standby ratings. Of interest to makers of AC-DC and DC-DC internal and external power supplies used in both industrial and consumer product sectors, the SO8 packaged device can also operate at switching frequencies as high as 500 kHz, affecting a reduction in transformer size leading to slimmer form factor design.

To help maximise power supply circuit efficiency, the ZXGD3105N8 functions as a proportional gate drive, which both protects against unnecessary MOSFET turn-off and reduces MOSFET turn-off propagation delay down to 15 ns, thereby minimising reverse current flow. This increased efficiency eases thermal design by reducing heatsink size and allowing a smaller PSU design with higher power density.
