The BL9315 is a high-efficiency, DC-to-DC step-down switching regulators, capable of delivering up to 3A of output current. The device operates from an input voltage range of 2.5V to 5.5V and provides an output voltage greater than 0.6V, making the BL9315 ideal for low voltage power conversions. Running at a frequency of 1.4MHz 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. The light-load mode enhances the light loading efficiency. The low noise output along with its excellent efficiency achieved by the internal synchronous rectifier, making BL9315 an ideal green replacement for large power consuming linear regulators. Internal soft-start control circuitry reduces inrush current. Short-circuit and thermal-overload protection improves design reliability. The BL9315 is available in ESOP8 package.
