Anachip AP1625
The AP1625 series are multi-functional step-down DC/DC converters with built-in speed, low ON resistance drivers. With a 270KHz switching frequency, the size of the external components can be reduced. Control switches from PWM to PFM during light loads with the AP1625 （PWM/PFM switchable） and the series is highly efficient from light loads to large output currents.| Part No. | AP1625 |

FEATURES
- Input voltage range:2.2V~8V（VOUT type） - Adjustable version（±2.5%） - Oscillator frequency: 270KHz（±15%） - High Efficiency: 92%（typ .） - Stand-by capability: ISTB＝3µA.（max .） - Soft-start time set-up externally type possible - Output voltage type possible（FB） - Package: SOT23-5 General Descriptions A more than 1A output current is possible using an externally connected transistor, coil, diode and capacitor. Output voltage is set-up by external resistor. （±2.5% accuracy）. In relation to soft-start time external capacitor regulated types. During stand-by time （ CE pin “LOW” ） ,current consumption is reduced to less than 0.5µA. With U.V.L.O internal, the external MOSFET. Will be forcibly switched off if used below the stipulated voltage. APPLICATIONS
