Murata’s CR series of cost effective DC-DC converters comes in industry standard packages with industry standard pinouts for onboard distributed power systems. Popular input and output voltages are available, and the galvanic isolation allows the device to be configured to provide an isolated negative rail in systems where only positive rails exist.
The CRV1 series is ideally suited for providing local supplies on control system boards with the added benefit of 3 kV DC galvanic isolation to reduce switching noise. Available in a SIP package with dual and single outputs, all of the rated power may be drawn from a single output rail provided the total load does not exceed 1 Watt.
The CRV2 series is available in industry standard SIP packaging, offering a power upgrade path from the 1 W CRV1 series.
The CRE1 series is a cost effective 1 W DC-DC converter with a wide temperature range guaranteeing startup from -40°C and full 1 Watt output at 85°C.
The CRL2 series is particularly suited to isolating and/or converting DC power rails. The galvanic isolation allows the device to be configured to provide an isolated negative rail in systems where only positive rails exist. The wide temperature range guarantees startup from -40°C and full 2 Watt output at 85°C. Pin compatibility with the NME and LME ensures ease of upgradeability.
The CRR1 series is ideally suited for providing single rail supplies on primarily digital boards with the added benefit of galvanic isolation to reduce switching noise. Surface mount technology and advanced packaging materials produce rugged, reliable performance over an extended temperature range from -40°C to 85°C.
