MPM3690-50A/B
16V, Dual 25A or Single 50A
DC/DC Power Module
DESCRIPTION
FEATURES
The MPM3690-50 is a dual 25A or single 50A
output power module that offers a complete
power solution with excellent load and line
regulation. The MPM3690-50 supports a 4V to
16V input voltage range and a 0.6V to 1.8V
output voltage range. The voltages at the
MPM3690-50’s two outputs can be set
separately by a single resistor per output.
Pin-Compatible Dual 25A and Single 50A
Output Power Modules

o MPM3690-50B Single 50A
4V to 16V Input Voltage Range
o 3.2V to 16V Input Voltage Range with
External 3.3V VCC Bias
0.6V to 1.8V Output Voltage Range
Ultra-Fast Transient Enabled by COT
Control
Adjustable Switching Frequency
Adjustable Soft-Start Time
Over-Current and Over-Voltage Protection
Differential Remote Sense for Both Output
Channels
The MPM3690-50 offers two configurations: the
MPM3690-50A has a dual 25A output, and the
MPM3690-50B has a single 50A output. The
MPM3690-50 is also pin-compatible with the
MPM3690-20A/B (dual 13A or single 26A) and
the MPM3690-30A/B (dual 18A or single 36A)
power modules.
Pin-Compatible with the MPM3690-20A/B
and MPM3695-30A/B
Available in a BGA Package
(16mmx16mmx5.18mm)
The MPM3690-50 adopts MPS’s proprietary,
multi-phase constant-on-time (MCOT) control,
which provides ultra-fast transient response and
minimizes the output capacitance.
APPLICATIONS
The MPM3690-50 integrates a monolithic
DC/DC converter, power inductor, and other
passive components, and is available in a BGA
(16mmx16mmx5.18mm) package,
