K78-LB Series switching regulators set new standards for cost vs performance

Relec Electronics is pleased to announce the introduction of K78xxJT-500R3-LB and K78xx-500R3-LB series switching regulators (K78-LB). Available as traditional 3 pin, through-hole packages, or compact surface mount (SMD), the LB series offers a step change drop in cost making them ideal for price-sensitive, high-volume applications.

High Efficiency / Low Cost

These high-efficiency switching regulators from Mornsun Power, and are ideal for use in space-constrained and cost-conscious designs. Both families feature input ranges up to 36Vdc with operating temperatures from -40 to +85°C and efficiencies up to 95% with no requirements for additional heatsinks.

Characteristics include low ripple and low noise operation (typ 50mV pp), with a MTBF of >2,000,000 hours. All models have short circuit protection as standard. They are also RoHS-compliant.

K78-LB series

The K78xx-500R3-LB regulators are supplied in an industry-standard SIP3 package and are pin-compatible with the LM78xx linear regulators and can be used to directly replace them. The K78xxJT-500R3-LB series buck converters come in a 12.00 x 12.00 x 4.50mm surface mount package and can be supplied either in tubes or as a tape and reel (T&R) option.

Wide Variety of Applications

The K78xxJT-500R3-LB and K78xx-500R3-LB series switching regulators find uses in a wide variety of projects including instrumentation, robotics, street lighting and IoT (Internet of things) applications.

Short Lead-times & Competitively Priced

The K78xxJT-500R3-LB and K78xx-500R3-LB are available today with the industry’s shortest lead-times (4 – 6 weeks in volume) and benchmark pricing.
