Working Principles

The TS34063CD C3G is a versatile DC-DC converter that can step-up, step-down, or invert the input voltage. It utilizes an internal power switch and an oscillator to generate a high-frequency switching signal. This signal controls the power flow through an inductor, capacitor, and diode network, resulting in the desired output voltage.

The feedback pin (FB) monitors the output voltage and adjusts the duty cycle of the internal power switch to maintain the desired voltage level. The timing resistor (RT) and timing capacitor (CT) connected to the RT/CT pin determine the switching frequency.

The error amplifier compares the feedback voltage with a reference voltage, allowing precise regulation of the output voltage. The COMP pin provides compensation to stabilize the feedback loop and improve overall performance.
