Available now from MicroPower Direct, the SRM7810 series is a family of ultra-miniature, point of load switching regulators that provide up to 1A of output current. These converters are specifically designed to replace inefficient linear regulators (LM78xx type) for board level applications that require miniature size, high efficiency, high reliability and low cost.

Two standard models operate over an input range of 4.75 to 20 VDC, providing tightly regulated outputs of 3.3 or 5 VDC. Output current for all models is 1A. Standard features include efficiency as high as 93%, very low noise operation and tight line/load regulation. All models feature over load protection, over temperature protection and continuous short circuit protection. The MTBF for both models (per MIL HDBK 217F) is greater than 2.0 Mhours.

The SRM7810 family is packaged in a miniature, Single-Inline-Package (SIP) case that is only 0.45 x 0.30 x 0.40 inches. They feature an industry standard pin-out and all case materials meet UL94-VO. Each model is specified for operation over the wide operating temperature range of -40°C to +70°C with no derating or heat sinking required (derated operation to +85°C is specified). Cooling is by free-air convection.

The SRM7810 series offers an ideal combination of miniature size, robust performance and low cost. They are an ideal replacement for inefficient linear POL regulators (which typically need heat sinking and/or airflow), providing reliable operation over a wide operating temperature range without any need of external heat sinking or board layout changes. Applications would include industrial process systems, remote or battery backed systems, test/lab instrumentation, robotic systems and board level power distribution subsystems.

MicroPower Direct products are designed to provide long, reliable field life. Considerable attention is given to the proper selection, derating, and layout of all circuit components. In addition, extensive reliability screening is also performed on all modules as a routine part of our production process.
