This product integrates the driver IC and Nex FET technology to plete the power stage switching function. The driver IC has a built-in selectable diode emulation function that enables DCM operation to improve light load efficiency. In addition, the driver IC supports ULQ mode that enables Connected Standby for Windows™ 8. With the PWM input in tri-state, quiescent current is reduced to 130 µA, with immediate response. When SKIP# is held at tri-state, the current is reduced to 8 µA (typically 20 µs is required to resume switching). This bination produces a high-current, high-efficiency, and highspeed switching device in a small 3.5-mm × 4.5-mm outline package. In addition, the PCB footprint has been optimized to help reduce design time and simplify the pletion of the overall system design.
