Murata has added a miniature 1.5-A SIP model to the Murata Okami family of non-isolated PoL converters. The OKR-T/1.5-W12-C is well suited for designs that require low load current with limited board space. In addition, this SIP-format, through-hole-mounted miniature device combines a wide input-voltage range with programmable output voltage to give engineers a high degree of flexibility in their designs. Part of the comprehensive Okami family of PoL DC-DC power converters, the OKR series offers designers a choice of 1.5-, 3-, 6-, and 10-A modules in a through-hole SIP format. The use of a common, industry-standard footprint and form factor across the product range helps simplify inclusion of the devices in both existing and new designs. Applications include powering ASICs, FPGAs, DSPs, microprocessors, and communications ICs in both datacom and industrial equipment. Based on 600-kHz synchronous buck topology, the OKR-T/1.5-W12-C offers high power-conversion efficiencies of 93% and also has the ability to drive up to 200 uF ceramic-capacitor loads. Output voltage is programmable from 0.591 to 6.0 V DC and converters are able to operate from a wide input-voltage range of 4.5 to 14 V DC. The OKR-T/1.5-W12-C delivers outstanding thermal derating performance, Other features include over-temperature and over-current protection, remote on-off control, and UVLO (under-voltage lock out). Overall dimensions are 10.4 x 10.16 x 6.1 mm (0.41 x 0.40 x 0.24 inches). Operating temperature range is - 40 to + 85 degrees C. The units are designed to meet UL/EN/EC 60950-1 safety and FCC EMI/RFI emission certifications and are RoHS-6 compliant. Murata
