Working Principles

The TPS61230ARNSR operates as a step-up DC-DC converter using a synchronous boost topology. It utilizes an inductor, a diode, and a switch to efficiently convert the input voltage to a higher output voltage. The integrated control circuitry ensures proper regulation and protection features.

During operation, the input voltage is applied to the VIN pin, and the switch (SW) controls the current flow through the inductor. By periodically opening and closing the switch, energy is stored in the inductor during the switch-on phase and released to the output during the switch-off phase. This process boosts the voltage to the desired level.

The feedback pin (FB) monitors the output voltage and adjusts the duty cycle of the switch to maintain a stable output. Additional features like soft-start, overcurrent protection, and undervoltage lockout enhance the overall performance and reliability of the device.
