MPM3690-30A/B
16V, Dual 18A or Single 36A
DC/DC Power Module
DESCRIPTION
FEATURES
The MPM3690-30 is a dual 18A or single 36A
output power module, which offers a complete
power solution with excellent load and line
regulation. The MPM3690-30 supports a 4V to
16V input voltage (VIN) range and a 0.6V to 3.3V
output voltage (VOUT) range. The voltage of the
MPM3690-30’s two outputs can be set
separately by a single resistor per output.
Pin-Compatible Dual 18A and Single 36A
Output Power Modules
o MPM3690-30A Dual 18A
o MPM3690-30B Single 36A
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 Constant-
On-Time (COT) Control
Adjustable Switching Frequency
Adjustable Soft-Start Time
Over-Current and Over-Voltage Protection
Differential Remote Sense for Both Output
Channels
The MPM3690-30 offers two configurations: the
MPM3690-30A has a dual 18A output, and the
MPM3690-30B has a single 36A output. The
MPM3690-30 is also pin-compatible with the
MPM3690-20A/B (dual 13A or single 26A) and
the MPM3690-50A/B (dual 25A or single 50A)
power modules.
Pin Compatible with the MPM3690-20 and
MPM3695-50
Available in a BGA (16mmx16mmx5.18mm)
Package
The MPM3690-30 adopts MPS’s proprietary,
multi-phase constant-on-time (MCOT) control,
which provides ultra-fast transient response and
minimizes the output capacitance.
APPLICATIONS
The MPM3690-30 integrates monolithic DC/DC
converter, power inductor, and other passive
components, and is available in a BGA
(16mmx16mmx5.18mm) package.
