MPM3682
18V 10A Step-Down Power Module
in 12x12x4mm QFN
DESCRIPTION
The MPM3682 is an easy-to-use fully integrated
10A 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. MPM3682 can deliver 10A output current
over a wide input supply voltage range with
excellent load and line regulation.
The MPM3682 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 MPM3682 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 MPM3682 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 MPM3682 has fully integrated protection
features that include over-current protection,
over-voltage protection and thermal shutdown.
