MPM3690-20A/B
16V, Dual 13A or Single 26A DC/DC Power Module
DESCRIPTION
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.
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.
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.
The MPM3690-20 integrates a monolithic DC/DC converter, power inductor, and other passive components. It is available in a BGA (16mmx16mmx5.18mm) package.
