DC/DC converters offer efficiencies up to 97%

Available in three different package formats – through hole, single in line, and surface mount – the 40A, 132W digital DC/DC converters offer effiencies up to 97.2%. Murata says their PMBus interface facilitates power management features not previously available in analogue PoL converters. By interfacing the OKD converter to the system's I2C bus, systems engineers 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. 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 an input voltage range from 4.5 to 14VDC, the OKDx-T/40-W12 output voltage is programmable from 0.6 to 3.3VDC. A GUI can be provided to assist the power engineer in designing a state of the art power system.
