MPQ2179A is a monolithic, synchronous, step-down, switch-mode converter with integrated internal power MOSFETs. It can achieve up to 3A of continuous output current (IOUT) across a 2.5V to 5.5V input voltage (VIN) range with excellent load and line regulation. The output voltage (VOUT) can be regulated to as low as 0.6V. The MPQ2179A is ideal for a wide range of applications including automotive clusters, telematics and infotainment systems, camera modules, key fobs, industrial supplies, battery powered devices. Constant-on-time (COT) control provides fast transient response and eases loop stabilization. Fault protections include cycle-by-cycle current limiting and thermal shutdown. The MPQ2179A requires a minimal number of readily available, standard external components and is available in a compact QFN-8 (1.5mmx2mm) package.
