Working Principles

The TC1301B-GFDVMFTR is a voltage regulator IC that converts an input voltage within the range of 2.5V to 6.0V into a regulated output voltage between 0.8V and 5.0V. It utilizes a switching regulator topology to achieve high efficiency and low dropout voltage.

The EN pin controls the enable/disable state of the regulator. When EN is high, the regulator is enabled and actively regulates the output voltage. Conversely, when EN is low, the regulator enters a low-power standby mode.

The FB pin provides feedback to the internal control circuitry, ensuring the output voltage remains stable and within the desired range. The SW pin is connected to an external inductor and capacitor to form a switching network, which allows for efficient voltage conversion.
