## Description

The Texas Instruments LM5122MH is a versatile DC DC switching controller designed for boost, flyback, forward, and SEPIC topologies. It features a wide input voltage range from 3V to 65V and can provide an output voltage up to 100V. The controller operates in current mode and offers features such as frequency synchronization, phase interleaving, and adjustable UVLO.

With a maximum duty cycle of 100% and a switching frequency up to 1 MHz, the LM5122MH is suitable for various power management applications. It includes robust 3A integrated gate drivers and adaptive dead-time control. The device operates within a temperature range of -40°C to 125°C and is available in thermally enhanced 20 or 24-pin HTSSOP packages.

Key electrical characteristics include a typical quiescent current of 0.004A and a low shutdown quiescent current of 9µA. It also provides a 1.2V reference with ±1% accuracy and programmable features like cycle-by-cycle current limit and hiccup-mode overload protection.
