The MP1609 is a monolithic, step-down switch-mode converter with built-in internal power MOSFETs. It achieves up to 8A of continuous output current (IOUT) from a 2.4V to 5.5V input voltage (VIN) range, with excellent load and line regulation. The output voltage (VOUT) can be regulated to as low as 0.4V.
The constant-on-time (COT) control scheme provides fast transient response and eases loop stabilization. Fault protections include cycle-by-cycle current limiting and thermal shutdown.
The MP1609 is ideal for a wide range of applications, including high-performance DSPs, wireless power, portable and mobile devices, and other low-power systems.
The MP1609 is available in QFN-7 (2mmx3mm) package, and requires a minimal number of readily available, standard external components.
