The MP9842 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a compact solution that achieves up to 2A of continuous output current with excellent load and line regulation over a wide 3.3V to 36V input supply range. The device operates in a current mode control scheme for fast transient response and cycle-by-cycle current limiting. It features a low 14μA quiescent current in sleep mode, making it suitable for battery-powered applications and automotive systems.
