MicroPower Direct is broadening its point-of-load product line with new regulators that are said to provide peak efficiency of 97 percent, with no heatsink required.
SOUTH EASTON, Mass.—To meet the demands of today’s industrial and embedded systems, engineers are increasingly shifting away from traditional linear regulators—not just to improve efficiency, but to reduce heat and minimize board complexity.
MicroPower Direct engineered its MSR78xx series of point-of-load (POL) switching regulators for exactly that need: reliable, high-efficiency regulation without the overhead of heatsinks or bulky packaging. The company recently introduced three new models in the series—the MSR7805BW (0.5A), MSR7810BW (1A), and MSR7820CW (2A)—that are designed as drop-in replacements for LM78xx linear regulators, the company said in a release.
The compact modules are reported to deliver up to 2A output current and a peak efficiency of 97 percent, with no heatsink required. They also offer a wide 6.5–36 VDC input range. All of this is achieved in a space-saving SIP3 package with integrated short-circuit and thermal protection, according to MicroPower Direct.
“Engineers are under pressure to shrink designs, cut heat, and keep costs in check,” said Amy Anahory, CEO of MicroPower Direct, in the release. “That’s where the MSR78xx series fits—it improves circuit thermal performance without complicating the rest of the design.”
The MSR78xx Series regulators provide full power operation from –40°C to +85°C. In addition to a compact SIP3 footprint for streamlined integration, the switching regulators offer a low-noise switching design, the company said.
“The MSR78xx series is tested to EN 55032 Class B EMC standards and meets key IEC 61000-4 immunity levels when used with the recommended input filter. The regulators are ideally suited for space-constrained, high-reliability designs across industries like industrial automation, test and measurement, and embedded power systems—including energy, medical, and defense-related applications,” the release stated.
MicroPower Direct is a U.S.-based, WOSB-certified (Women-Owned Small Business) supplier of high-performance power supplies to OEMs for industrial, medical, aerospace, and electronics applications.
“Since 1999, we’ve helped engineers meet tough design goals with reliable, cost-effective AC/DC power supplies, DC/DC converters, point-of-load regulators, and IGBT drivers that are easy to specify and ready to ship,” the company stated in the release.
