Working Principles

The TPS61052DRCT operates as a boost converter by utilizing an internal switch to control the energy transfer from the input to the output. When the switch is closed, energy is stored in an inductor, and when it opens, the stored energy is transferred to the output capacitor, resulting in a higher output voltage.

The feedback pin monitors the output voltage and adjusts the duty cycle of the internal switch to maintain the desired output voltage level. The enable pin provides control over the device's operation, allowing for power management and shutdown when necessary.
