Working Principles

The SRP120LF is a step-down DC-DC converter that efficiently regulates the input voltage to a lower, stable output voltage. When enabled, the internal control circuitry adjusts the duty cycle of the switch node to achieve the desired output voltage. The feedback mechanism continuously monitors the output voltage and adjusts the duty cycle as necessary to maintain regulation.

Detailed Application Field Plans

The SRP120LF is well-suited for various battery-powered applications such as portable devices, IoT sensors, and handheld instruments. Its low quiescent current and wide input voltage range make it suitable for energy-efficient designs requiring long battery life.
