The ACP2825 is a high-efficiency, DC-to-DC step-down switching regulators, capable of delivering up to 1.2A of output current. The device operates from an input voltage range of 2.5V to 6V and provides an output voltage from 0.6V to VIN, making the ACP2825 ideal for low voltage power conversions. Running at a fixed frequency of 1.5MHz allows the use of small external components, such as ceramic input and output caps, as well as small inductors, while still providing low output ripples. This low noise output along with its excellent efficiency achieved by the internal synchronous rectifier, making ACP2825 an ideal green replacement for large power consuming linear regulators. Internal soft-start control circuitry reduces inrush current. Short-circuit and thermal-overload protection, input over voltage and input under voltage lockout protection improves design reliability. The device is available in SOT25 package.
