The LM25118MH from Texas Instruments is a versatile DC DC switching controller designed for Buck-Boost applications. It supports a wide input voltage range from 3V to 42V, making it suitable for various power supply designs. The controller can regulate output voltages from 1.23V up to 38V.
Key features include a programmable switching frequency up to 500 kHz, a maximum duty cycle of 98%, and a typical quiescent current of 4.5 mA. The operating temperature range is -40°C to 125°C. The device is housed in a 20-pin HTSSOP package with exposed pad dimensions of 6.5 mm x 6.4 mm.
This controller utilizes Emulated Peak Current Mode Control and offers smooth transitions between step-down and step-up modes. It integrates high and low-side gate drivers, a programmable soft-start time, and an ultra-low shutdown current. The wide bandwidth error amplifier and 1.5% feedback reference accuracy contribute to its performance.
