Switching frequency200-1000 kHz
Output 15 V
IC revision1.01

Description

The MPM3686 is an easy-to-use fully integrated 20A 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 QFN12mmX15mmX4mm package. This total power solution needs as few as two external components (one resistor and one capacitor) to work. MPM3686 can deliver 20A output current over a wide input supply voltage range withexcellent load and line regulation.The MPM3686 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 MPM3686 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 MPM3686 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 MPM3686 has fully integrated protection features that include over-current protection, over-voltage protection and thermal shutdown
