PoL product line broadened with high-efficiency switching regulators

MicroPower Direct has released three new models in its MSR78xx series of point-of-load (PoL) switching regulators. Designed as drop-in replacements for LM78xx linear regulators, these compact modules deliver up to 2A output current, peak efficiency of 97%, and a wide 6.5–36VDC input range – all in a space-saving SIP3 package with integrated short-circuit and thermal protection.

"Engineers are under pressure to shrink designs, cut heat, and keep costs in check," said Amy Anahory, CEO of MicroPower Direct. "That's where the MSR78xx series fits – it improves circuit thermal performance without complicating the rest of the design."

To satisfy the demands of today's industrial and embedded systems, engineers are increasingly shifting away from conventional linear regulators – not just to improve efficiency but to lower heat and minimise board complexity. The series is engineered to meet that exact need, offering reliable, high-efficiency regulation without the overhead of heatsinks or bulky packaging.

The new models include the MSR7805BW (0.5A), MSR7810BW (1A), and MSR7820CW (2A).

Key features:

• Up to 97% efficiency (no heatsink required)
• Short-circuit and over-temperature protection
• Full power operation from –40C to +85C
• Low-noise switching design

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. These regulators are ideal for space-constrained, high-reliability designs across various industries, including industrial automation, test and measurement, and embedded power systems, such as those in energy, medical, and defence-related applications.
