Working Principles

The MP2162AGQH-P is a synchronous step-down converter that utilizes a pulse-width modulation (PWM) control scheme. It takes an input voltage within the range of 4.5V to 18V and efficiently converts it to a lower, adjustable output voltage between 0.6V and 5.5V. The converter operates at a switching frequency of 1.2MHz, allowing for compact external components.

The IC uses a high-side and low-side MOSFET pair to regulate the output voltage. The feedback voltage (FB) pin monitors the output voltage and adjusts the duty cycle of the internal switches to maintain the desired output voltage. The soft-start/ tracking (SS/TR) pin controls the startup behavior and can be used for sequencing multiple converters.
