The CSD97395Q4M NexFET power stage design is highly optimized for high power, high density synchronous buck converters. This product integrates a driver integrated circuit (IC) and NexFET technology to complete the power stage switching function. The driver IC has a built-in optional diode emulation function that enables discontinuous conduction mode (DCM) operation to improve light load efficiency. In addition, the driver IC supports ULQ mode, which supports the connected standby function for Windows 8. With 3-state PWM inputs, quiescent current is reduced to 130µA and immediate response is supported. When SKIP# is held in tri-state, the current can be reduced to 8µA (typically 20µs to resume switching). This combination enables high current, high efficiency and high speed switching in a small 3.5 x 4.5mm form factor package. Additionally, the printed circuit board (PCB) package has been optimized to help reduce design time and simplify overall system design completion.
