Available now from MicroPower Direct, the D300RU series is a family of compact 3W DC/DC converters. They feature an ultra-wide 4:1 input voltage range, high efficiency, tight output regulation and high reliability.
Twenty one models operate from wide 4:1 inputs of 4.5 to 18, 9 to 36, or 18 to 75 VDC, providing single and dual outputs of 3.3, 5, 12, 15, ±5, ±12 or ±15 VDC. Standard features include a ±1% max line/load regulation, an input/output isolation of 1,600 VDC, continuous short circuit protection, and efficiency as high as 81%. Also standard is a remote ON/OFF control input. The MTBF (per MIL HDBK 217F) of the D300RU series is greater than 800 khours.
The D300RU family is packaged in a miniature, Single-Inline-Package (SIP) case. The pin-out is industry standard. Each model is specified for operation over the wide operating industrial temperature range of -40°C to +85°C. Cooling is by free-air convection.
The D300RU series is an ideal solution for a wide variety of board level industrial power applications requiring 3W of output power, a very wide input voltage range, miniature package size and low cost. Applications would include process control systems, board level data acquisition systems, industrial robotics 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.
