Switching regulators drop in to save BoM

Relec Electronics has introduced Mornsun’s K78xxJT-500R3-LB and K78xx-500R3-LB series switching regulators. The family is available in a choice of mounting options and is designed to offer engineers reliable models for price-sensitive, high volume, high efficiency applications.

Both families feature input ranges up to 36VDC and outputs from three to 15V. Operating temperature range is -40 to 85°C, while efficiencies are up to 95 per cent with no requirements for additional heatsinks, even when operating at 85°C.

The regulators are supplied in a SIP3 package. They are pin-compatible with LM78xx linear regulators and can be used as direct replacements. The K78xxJT-500R3-LB series buck converters are in a 12.00 by 12.00 by 4.50mm surface mount package and can be supplied either in tubes or tape and reel.

The regulators suit cost-sensitive, space-constrained applications demanding reliable non isolated DC/DC conversion, such as instrumentation, robotics, street lighting and IoT.

The products are available on four to six weeks lead time in volume.
