MPM3690-20A/B
16V, Dual 13A or Single 26A
DC/DC Power Module
DESCRIPTION
FEATURES
The MPM3690-20 is a dual 13A output or single
26A output power module that offers a complete
power solution with excellent load and line
regulation. The MPM3690-20 supports an input
range between 4V and 16V and an output range
between 0.6V and 3.3V. The voltage of the
MPM3690-20’s two outputs can be set
separately via a single resistor at each output.
Pin-Compatible Dual 13A or Single 26A
Output Power Modules:
o MPM3690-20A: Dual 13A Output
o MPM3690-20B: Single 26A Output
4V to 16V Input Voltage Range
o 3.2V to 16V Input Voltage Range with
External 3.3V VCC Bias
0.6V to 3.3V 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 MPM3690-20 offers two configurations. The
MPM3690-20A is dual 13A output, while the
MPM3690-20B is single 26A output. The
MPM3690-20 is also pin-compatible with the
MPM3690-30A/B (dual 18A or single 36A output)
and MPM3690-50A/B (dual 25A or single 50A
output) power modules. See the Ordering
Information section on page 2 for more details.
Pin-Compatible with the MPM3690-30 and
MPM3695-50
Available in a BGA (16mmx16mmx5.18mm)
Package
The MPM3690-20 adopts MPS’s proprietary,
multi-phase constant-on-time (MCOT) control,
which provides ultra-fast transient response and
minimizes the output capacitance.
APPLICATIONS
The MPM3690-20 integrates a monolithic
DC/DC converter, power inductor, and other
passive components. It is available in a BGA
(16mmx16mmx5.18mm) package.
