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.

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.

Here at Relec we are a happy to offer free of charge samples, many of which we have in stock for immediate delivery.  We will also offer full technical support to help integrate the converters into your design as well as finding solutions for other aspects of your power topology…
