The LM25118MHE/NOPB from Texas Instruments is a versatile DC DC switching regulator controller. It features a wide input voltage operating range from 3V to 42V, making it suitable for various power supply designs. The controller supports both step-up and step-down (Buck-Boost) topologies, allowing it to maintain output voltage regulation regardless of whether the input voltage is higher or lower than the desired output.
Key electrical specifications include a programmable switching frequency up to 500kHz, a maximum duty cycle of 75%, and a quiescent current of 0.0045A typical. It offers control features such as Enable, Frequency Control, Ramp, and Soft Start, along with clock synchronization capability. The device operates within a temperature range of -40°C to 125°C (TJ).
Packaged in a 20-pin HTSSOP, the LM25118MHE/NOPB is designed for surface mount applications. Its design facilitates the implementation of high-performance, cost-efficient Buck-Boost regulators with minimal external components. The controller integrates high and low-side gate drivers and features an ultra-low shutdown current.
