Digital 40-Amp 132-Watt PoL DC-DC Converter
Murata Power Solutions announced today the addition of the OKD series of non-isolated point-of-load (PoL) dc-dc converters. 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 97.2% efficient (typical), 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 PMBusâ„¢ 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 designed for use in telecommunications, networking, and distributed power applications.
