Working Principles

The MAX1832EUT#TG16 is a step-up DC-DC converter that efficiently boosts the input voltage to a higher level. It utilizes an internal synchronous rectification mechanism to minimize power losses during conversion, resulting in high efficiency.

The device operates by controlling the duty cycle of an internal switch connected to an external inductor. When the switch is closed, energy is stored in the inductor. When the switch opens, the stored energy is transferred to the output capacitor, raising the output voltage.

The converter's feedback pin (FB) monitors the output voltage and adjusts the duty cycle accordingly to maintain a stable output. The enable pin (EN) allows the device to be turned on or off as needed.
