The MPM3680 is an easy-to-use fully integrated 6A step-down DC/DC power module. It integrates the DC/DC converter, power inductor, input/output capacitors and the necessary resistors/capacitors in a compact QFN 12mmX12mmX4mm package. This total power solution needs as few as two external components (one resistor and one capacitor) to work. MPM3680 can deliver 6A output current over a wide input supply voltage range with excellent load and line regulation. The MPM3680 uses Constant-On-Time (COT) control to provide fast transient response and ease the loop stabilization. The default under voltage lockout threshold is internally set around 4.1V, but a resistor network on the enable pin can increase this threshold. The MPM3680 has an internal LDO to power the control circuits and the integrated power devices. This LDO can be disabled by an external 5V to boost the efficiency. The MPM3680 has an internal about 3ms soft start (SS) timer. It can be increased with an extra SS capacitor. An open drain power good signal indicates that the output voltage is within nominal voltage range. The MPM3680 has fully integrated protection features that include over-current protection, over-voltage protection and thermal shutdown.
