Murata unveils 420W, PMBus compliant quarter brick
1 min read
Murata has introduced the UDQ series of isolated, digitally controlled dc/dc converters.
Incorporating a 32bit ARM7 processor, the 420W regulated UDQ2204/001 model is the first in the series to include a PMBus compatible digital interface.
The module is an isolated, fully regulated 420W to 12Vout quarter brick that supports the TNV input voltage range of 36 to 75V, with a typical efficiency of 95.5%.
The module provides a digital interface supporting the PMBus standard for digital power management in systems used in applications such as MicroTCA, servers, storage, networking equipment, POE, wireless networks, industrial and test equipment.
Murata says the PMBus interface facilitates power management features not previously available in an isolated, modular quarter brick dc/dc converter. By attaching the UDQ to the system's I2C bus, engineers can monitor Vin, Iin, Vout, Iout, and operating temperature.
The PMBus can be used to set warning flags for temperature, Vin, Vout, Iout and allows the user to customise parameters such as Vout, Vin turn on/off thresholds, output over voltage protection, output current limit and ramp up characteristics.
