MLSR05DFW 3D

MLSR05DFW Ultra-Miniature Surface Mount, 0.5A POL Regulator

Available now, the MSR05DFW is a micro-size switching voltage regulator that provides a tightly regulated output of 0.5A. All models are cased in a miniature Dual Flat No-lead (DFN) package measuring only 0.35 x 0.27 x 0.12 in (9.0 x 7.0 x 3.1 mm). A size reduction that allows the MLSRO5DFW to operate while using 57% less board layout space. In total volume, it achieves about an 85% reduction. All with improved performance.

MR4011SRU Ultra-Wide Input, Railway/Transit DC/DC Converters

Six standard models operate from wide 40 VDC to 160 VDC (110 VDC nominal) inputs, providing tightly regulated single outputs of 3.3, 5, 12, 15, 24 or 48 VDC. Standard features include line/load regulation less than 1.0%, I/O isolation of 3,000 VDC, a remote control input and efficiency as high as 91%. They are protected for output short circuit faults and output over current faults. All models comply with multiple industry standards including EN 62368, EN 50155 and EN 55032. The MTBF (per MIL HDBK 217F) is greater than 500 khours.

MLSR192K-16A Miniature Surface Mount, 16A POL Switching Regulator

The MLSR192K-16A operates from an 8.3 to 14 VDC input, producing a single tightly regulated output at up to 16A. The output can be adjusted over a range of 0.7525V to 5.0V with a simple trim. Standard features include efficiency as high as 95%, low noise operation and tight line/load regulation. Protection against short circuit and over current faults is standard. The MSR192K-16A is protected against short circuit and over current faults. A control input allows the unit to be turned on/off remotely.
