300 W digital DC/DC power module

31 March 2021 Power Electronics / Power Management

The MPC1100A-54-0000 from Monolithic Power Systems (MPS) is a high-efficiency, non-isolated LLC-DCX power card module with a fixed 10:1 transformer turns ratio. The device operates from a 40 V to 60 V d.c. primary bus and has a 4 V to 6 V output voltage. It can deliver up to 300 W of power.

The module employs MPS’s MP2981 (a digital LLC controller) and MP8500 (a smart synchronous rectifier). These devices can adjust the pulse width modulation to optimise the MPC1100A54-0000, and ensure that it works at the resonant frequency.

The built-in multiple-time programmable (MTP) memory can store and restore device configurations. The fault status, input and output voltage, current, and temperature can be easily monitored via the PMBus/I2C interface.

The MPC1100A-54-0000 is available in a surface-mount (27 x 18 x 6 mm) package.
