Murata has announced the addition of the OKD series of non-isolated point-of-load (PoL) DC/DC converters from Murata Power Solutions. Available in three different package formats, through-hole, single-in-line, and surface mount, the OKDx-T/40 is a 40 Amp, 132 Watt digital DC/DC converter. These highly efficient (typically 97.2%), fully regulated converters offer a high power density and measure just 30.85 x 20.0 x 8.2 mm.
The PMBus interface facilitates power management features not previously available in analogue PoL converters. By interfacing the OKD converter to the system’s I2C bus, a systems engineer can monitor critical system-level performance requirements that include Vin, Iin, Vout, Iout, and operating temperature. The PMBus can also be used to set warning flags for temperature, Vin, Vout, and 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, to name a few.
Advanced converter design features include digital current sharing (full power, no derating), non-linear transient response, optimised dead time control, synchronisation, and phase spreading.
Accommodating the wide input voltage range from 4.5 to 14 VDC, the OKDx-T/40-W12 output voltage is programmable from 0.6 to 3.3 VDC. A GUI (Graphical User Interface) can be provided to assist the power engineer in designing a state-of-the-art power system.
The OKD series is intended for use in telecommunications, networking, and distributed power applications.
