The OKDx-T/40 series of non-isolated point-of-load (PoL) DC/DC converters from Murata Power Solutions is available in three different package formats, through-hole, single-in-line, and surface mount. It is rated 40 Amp, 132 Watt. 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 analog 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 customize 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, optimized dead time control, synchronization, 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 ideal for use in telecommunications, networking, and distributed power applications.
Lead-time is from stock to 12 weeks, with pricing in the range of $16.90 for OEM quantities.
