WD1012EA-5

WD1012EA-5/TR 1.5MHz, 600mA Synchronous Step-Down Regulator in SOT General Description The WD1012EA is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. The 2.7V to 5.5V input voltage range makes the WD1012EA ideally suited for single Li-Ion battery-powered applications. Supply current with no load is 22ȝA, dropping to <1ȝA in shutdown. PWM (Pulse Width Modulation) operation provides very low output ripple voltage for noise sensitive applications. 100% duty cycle capability provides low dropout operation, extending battery life in portable systems. The switching frequency is internally set at 1.5MHz, allowing the use of tiny surface mount inductors and capacitors. Low output voltages are easily supported with the 0.6V feedback reference voltage. The WD1012EA is available in SOT23 package. The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. Ordering Information Top...
