DC to DC Power Supplies (Converters)
Digitally Controlled POL DC/DC Converters deliver 50 A/165 W.
Press Release Summary:
Supplied in 30.85 x 20.0 x 8.2 mm module, OKDx-T/50 series accommodates 4.5–14 Vdc input and provides configurable output from 0.6–3.3 Vdc. Typ efficiency is 97.2% at 5 Vin, 3.3 Vout and with 50% load. Available in through-hole, single-in-line, and SMT formats, converters can be configured and monitored using PMBus commands. Standard features include Dynamic Loop Compensation, Non-Linear Transient Response, phase spreading, and dead time control.
Original Press Release:
Murata Adds Highly Efficient 50 Amp Digitally Controlled POL DC/DC Converter to Okami Line-up
Hoofddorp, Netherlands – Murata today announced the OKDx-T/50 series of 50 Amp digitally controlled point-of-load (POL) DC-DC converters from Murata Power Solutions. These converters, adding to Murata’s Okami range of non-isolated converters are capable of delivering 50 A / 165 Watt from a high power density module measuring only 30.85 x 20.0 x 8.2 mm. Available in three different package formats, through-hole, single-in-line and surface-mount, the converters can be configured and monitored using industry standard PMBus commands. These POLs have exactly the same footprint as the 40Amp OKDx-T/40 series released by Murata in September and have 25% higher power density. In addition to all the features of the 40A, these series also have ‘Dynamic Loop Compensation’, where the PID parameters of the control loop are automatically calculated and configured depending on the operating conditions and output filter. Another additional feature is the Non-Linear Transient Response that decreases response time and output voltage deviation. Other notable functions include phase spreading to reduce input capacitance requirements & efficiency losses and optimized dead time control that constantly adjusts dead time non-overlap in order to minimize duty cycle and maximize efficiency. Digital current sharing enables 100% current sharing accuracy with up to 7 POLs in parallel.
The OKDx-T50 series accommodates input voltages in the range 4.5 to 14 VDC and provides a configurable output voltage from 0.6 to 3.3 VDC. Typical efficiency is 97.2% at 5Vin, 3.3Vout and with 50% load.
Standard safety features are output short circuit, over current, output over voltage and input under voltage protection. Power good, remote sense and remote on/off are also included.
Typical applications for the OKDx-T/50 are for use in a broad range of telecommunications, wireless infrastructure and data networking equipment
