DC/DC Converters - MicroPower Direct


Now available from MicroPower Direct, the LF500RW series is a family of miniature SMT mountable 5W DC/DC converters. These converters provide high performance features such as a wide 2:1 input range, tight line/load regulation, output power/overload protection and low noise operation; in a miniature SMT package.
Twenty one models operate from wide 2:1 inputs of 9-18V, 18-36V and 36-75V; providing single and dual outputs of 3.3, 5, 12, 15, ±5, ±12 or ±15 VDC. Standard features include efficiency as high as 85%, an input/output isolation of 1,500 VDC, tight line/load regulation and low noise operation. All models have continuous short circuit protection (with autorecovery), output power protection, and include a remote On/Off control input. The MTBF (per MIL HDBK 217F) of the LF500RW series is greater than 1.0 Mhours.
The LF500RW family is packaged in a miniature, SMT case (compatible with automated assembly equipment). The pin-out is industry standard. Operation for all models is specified for operation over the wide operating temperature range of -40°C to +71°C with no derating or heat sinking required. Cooling is by free-air convection.
With its combination of high performance features, miniature size and economy, the LF500RW series is an ideal choice for space critical power conversion applications requiring low component cost, reliable field operation and miniature packaging. Applications would include data acquisition subsystems, data processing equipment, battery powered or battery backed equipment, industrial control equipment, and board level power distribution subsystems.
