There are no external components Up to 1A output current required. This makes it perfect for embedded systems that need +5V supply. High efficiency Thermal shutdown and current limit The board features innovations that set it protection apart from other supply board. Innovations Power-on LED feature like thermal shutdown, current limit Small and compact in size protection and power-on LED. The module Four mounting holes on each corner can be easy to interface via male or female Male and female output headers headers. +7 to +12VDC wall adapter can be use as an input via 2.5mm power jack. The board is small can compact in size 2.20 x 1.70 inches. The MR-MINI-PWR5 is designed base on LM2575-5 IC. It is monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 1A load with excellent line and load regulation. The LM2575 series offers a high-efficiency replacement for popular three-terminal linear regulators. It substantially reduces the size of the heat sink, and in many cases no heat sink is required. Other features include a guaranteed +/-4% tolerance on output voltage within specified input voltages and output load conditions, and +/-10% on the oscillator frequency. External shutdown is included, featuring 50 A (typical) standby current. The output switch includes cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions. Copyright 2007 MicroResearch GRAVITECH GROUP WWW.GRAVITECH.US
