PoL switching regulator protects from circuit faults
The latest switching regulator from Micropower Direct is the MLSR192K-16A. This miniature surface mount, 16A point of load (PoL) switching regulator provides up to 16A of output current.
It has an industry standard pin-out, and is characterised by high efficiency, wide temperature operation, protection from circuit faults and low cost, says Micropower Direct.
The MLSR192K-16A operates from an 8.3 to 14V DC 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 per cent, 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. (The regulator is available with positive or negative logic for this feature.)
The mean time between failure (MTBF) of the MSR192k-16A series is greater than one Mhours (per MIL HDBK 217F).
The MSR192k-16A is fabricated as a miniature, unpotted (open board) unit and measures 33 x 13.5 x 8.3mm (1.299 x 0.531 x 0.327 inches). The pin-out is industry standard.
Each model is specified for operation over the wide industrial operating temperature range of -40 to +85 degrees C with no heat sinking required. Cooling is by free-air convection.
All MicroPower Direct products are designed to provide long, reliable field life and the company performs extensive reliability screening on all products as a routine part of its production process.
