Description
The MPQ2178A is a monolithic, step-down switch-mode converter with integrated internal power MOSFETs. It can achieve up to 2A 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 MPQ2178A 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), short-circuit protection (SCP) with hiccup mode, and thermal shutdown. The MPQ2178A requires a minimal number of readily available, standard external components, and is available in an ultra-small QFN-8 (1.5mmx2mm) package.
