Working Principles

The MAX4996LETG+T is a voltage regulator IC that converts an input voltage within the range of 2.7V to 5.5V into a regulated output voltage between 0.8V and 3.6V. It achieves high efficiency by utilizing a synchronous buck converter architecture. The IC operates at a switching frequency of 1.2MHz, allowing for compact external components.

The enable pin (EN) controls the operation of the regulator. When EN is high, the regulator is enabled, and it enters a low-power shutdown mode when EN is low. The feedback pin (FB) provides a voltage reference for regulating the output voltage. The soft-start/tracking pin (SS/TRK) allows for controlled startup and tracking of the output voltage.
