Working Principles

The TPS61050DRCR operates as a boost converter, utilizing a switching regulator topology. It employs an internal power MOSFET switch to control the energy transfer from the input to the output. The device operates in a pulse-width modulation (PWM) mode, where the duty cycle of the switch is adjusted to regulate the output voltage.

When the input voltage is applied, the internal switch rapidly turns on and off, creating a square wave voltage at the switching node. This square wave is then filtered and stepped up to the desired output voltage level using an inductor and capacitor combination. The feedback pin monitors the output voltage and adjusts the duty cycle accordingly to maintain a stable output.
