DESCRIPTION
The MPM3683-20 is an easy-to-use, fully
integrated, step-down DC/DC power module.
The MPM3683-20 offers a complete power
solution that achieves up to 20A of peak
current. It integrates a DC/DC converter, power
inductor, and passive components. The
MPM3683-20 can deliver the output current
(IOUT) across a wide input voltage (VIN) supply
range, with excellent load and line regulation.
The MPM3683-20 uses constant-on-time (COT)
control to provide fast transient response and
ease loop stabilization.
The operating switching frequency (fSW) can be
set to 600kHz, 800kHz, or 1000kHz with the
MODE pin. This allows fSW to remain constant,
regardless of VIN or the output voltage (VOUT).
The MPM3683-20 features a configurable softstart
time (tSS) with one capacitor. An opendrain
power good (PG) signal indicates whether
VOUT is within the nominal voltage range.
The MPM3683-20 has fully integrated, nonlatch
protection features including over-current
protection (OCP), over-voltage protection
(OVP), and over-temperature protection (OTP).
The MPM3683-20 is available in a compact
FCM LGA-29 (7mmx7mmx4.4mm) package.
