PMBus compliant PoL DC/DC converters launched

The OKD series of digital PoL DC/DC converters from Murata is expanding with the 90A/162W OKDx-T/90 series.

According to the company, this is the highest current-rated product in the OKD series. The module is specified to operate over a Vin range of 7.5 to 14V and provides a user-adjustable Vout in the range of 0.6 to 1.8V DC with an efficiency of 94%.

The OKDx-T/90 is available in three different package configurations: 50.8 x 9.51 x 19.05mm SIP; horizontal mounting through-hole; and 50.8 x 19.05 x 10mm SMT.

Critical performance parameters are accessible through the PMBus via the Power Designer GUI software. The OKDx-T/90 operates over a Vin range from 7.5 to 14V; Vout can be adjusted from 0.6 to 1.8V, with a typical efficiency of 94% with 12Vin, at 1.8Vout and 50 % load.

The converter’s non-linear transient response is said to improve the dynamic response time, reducing Vout deviation due to large load changes, as well as phase spreading, which reduces input capacitor requirements and efficiency losses.

The synchronisation feature eliminates beat frequency reflection, resulting in less EMI filtering, and digital current sharing ensures near 100% current sharing accuracy with up to four modules operating in parallel.

The converters provide dynamic loop compensation and additional standard features include output short circuit, over current, over voltage, over temperature, and input under voltage protection.

According to the company, all the standard and advanced features can be configured via the Power Designer software, which includes a high-precision simulation tool.

The converters are suitable for any application requiring high current processor power, particularly in areas such as networking, computing/servers, telecom, powering FPGAs, CPUs, programmable logic, mixed voltage systems, advanced computing, and all distributed power applications.
