Features

* automatic shifting to power saving PFM Mode operation at light loads. Antiringing control circuitry reduces EMI concerns by damping the inductor in discontinuous mode, and the devices feature low shutdown current of under 1μA. The A7508 is available in SOT-26 Package FEATURES
* Up to 93% Effici

Applications

* with input voltages above 4.5V which could exhibit an overload or short-circuit condition, a RC Snubber circuit is required between the SW pin and GND. The recommended parameters are R3=2Ω, C5=1nF. The circuit can be seen in Figure 3. Figure 3.Vin>4.5V REV1.1 - DEC 2011 RELEASED, AUG 2014 UPDATED
