MPQ8616-12

The MPQ8616 is fully integrated high frequency synchronous rectified step-down switch mode converter. It offers very compact solutions to achieve 6A/12A output current from a 3V to 6V input with excellent load and line regulation. Constant-On-Time (COT) control mode provides fast transient response and eases loop stabilization. The MPQ8616 can operate with a low-cost electrolytic capacitor and can support ceramic output capacitor with external slope compensation. Operating frequency is programmed by an external resistor and is compensated for variations in VIN. It is almost constant with all the input voltage and output load conditions. Under voltage lockout is internally set at 2.8 V, but can be increased by programming the threshold with a resistor network on the enable pin. The output voltage startup ramp is controlled by the soft start pin. A power good signal indicates the output is within its nominal voltage range. Full fault protection including OCP, SCP, OVP UVP and OTP is provided by internal comparators. The MPQ8616 requires a minimum number of readily available standard external components and are available in QFN3x4 packages.
