LTC4444-5 OPERATION Overview The LTC4444-5 receives ground-referenced, low voltage digital input signals to drive two N-channel power MOSFETs in a synchronous buck power supply configuration. The gate of the low side MOSFET is driven either to V depending on the ...
Page 9
OPERATION pull-down on the driver outputs is the prevention of cross- conduction current. For example, when BG turns the low side (synchronous) power MOSFET off and TG turns the high side power MOSFET on, the voltage on the TS pin ...
