... NCP5369 Integrated Driver and MOSFET The NCP5369 integrates a MOSFET driver, high−side MOSFET and low−side MOSFET into 40−pin QFN package. The driver and MOSFETs have been optimized for high−current DC−DC buck power conversion applications. The NCP5369 integrated solution greatly reduces package parasitics and board space compared to a discrete component solution ...

... The bootstrap capacitor is recharged when the switch node goes low during the next cycle. Zero Current Detect When ZCD_EN# is set high, the NCP5369 will operate in normal PWM mode. When ZCD_EN# is set low, zero current detect (ZCD) will be enabled. If PWM goes high, GH will go high after the non− ...
