Working Principles

The MAX1823HEUB+T is a high-efficiency step-up DC-DC converter that boosts the input voltage to a higher output voltage. It utilizes a switching regulator topology to efficiently convert the input power to the desired output voltage. The converter operates at a high switching frequency of 1.2MHz, allowing for smaller external components and reducing overall circuit size.

The device features an enable pin (EN) that can be used to control the converter's operation. When the EN pin is low, the converter enters a low-power shutdown mode, drawing minimal current. This feature is particularly useful in battery-powered applications to conserve energy.
