Description

The AW37420 is a synchronous step-down buck DC-DC converter with high efficiency ａｎｄ low power consumption. The device integrates switches capable of delivering an output current up to 2 A. The device operates at typically 1.5 MHz frequency pulse width modulation (PWM) at moderate to heavy load currents. At light load, the device automatically converts to Power Save Mode (PSM) to maintain high efficiency over the entire load current range. Ｉｎ shutdown, the current consumption less than 2 μA. The AW37420 provides an adjustable output voltage via an external resistor divider. It has internal soft start circuit to limit the inrush current during startup. Other features ｌｉｋｅ over current protection, over temperature protection ａｎｄ power good are built-ｉｎ. The device is available ｉｎ DFN 2X2-8L, SOT23-5L ａｎｄ SOT23-6L package.
