6 and 10 Amp Models Added to PoL DC/DC Converter Series

Tue, 01/26/2010 - 8:07am
The 6A OKR-T/6 and the 10A OKR-T/10-W12 are the latest additions to Murata Power Solutions' range of Okami™ non-isolated Point-of-Load (PoL) DC/DC power converters. The SIP packaged though-hole mounting miniature devices combine a wide input voltage range with programmable output voltage to give engineers a high degree of flexibility in their designs.

The Okami range of PoL DC/DC power converters offers designers a choice of 3A, 6A and 10A modules in both through-hole and surface mount formats. The use of common, industry-standard pinouts across the range helps simplify inclusion of the devices in both existing and new designs. Applications include the powering of ASICs, FPGAs, DSPs, microprocessors and communications ICs in both datacom and industrial equipment.

Based on 600 kHz synchronous buck topology, the OKR-T/6 and the OKR-T/10-W12 offer high power conversion efficiencies of 93% and 92% respectively. Both modules are able to drive up to 200 æF capacitive loads.

Output voltage is programmable from 0.591 to 6.0 VDC and the modules are able to operate from a wide input voltage range of 4.5 to 14 VDC. The OKR-T/6 and the OKR-T/10-W12 deliver good thermal derating performance and feature over temperature and over current protection, On/Off control, and under voltage lock out (UVLO).

Overall dimensions for both are 0.41 inches (10.4 mm) x 0.65 inches (16.5 mm) x 0.3inches (7.62 mm).
