Description
The MPQ2179A is a monolithic, step-down switch-mode converter with integrated internal power MOSFETs. It can achieve up to 3A of output current (IOUT) across a 2.5V to 6V 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.
Constant-on-time (COT) control provides fast transient response and eases loop stabilization. Full protection features include cycle-by-cycle current limiting, output over-voltage protection (OVP), 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.
