Specifications of MR-MINI-DUALPWR5

• Rohs: yes
• Product: Power Supply Boards
• Tool Is For Evaluation Of: LM2575-5
• Input Voltage: 7 V to 12 V
• Output Voltage: +/- 5 V
• Description/function: MR-MINI-DUALPWR5 is a dual + 5 V and -5 V switching power supply
• Output Current: 1 A

The MR-PWR5 is a +5VDC power supply
board. There are no external components
required. This makes it perfect for embedded
systems that need +5V supply.
The board features innovations that set it
apart from other supply board. Innovations
feature like thermal shutdown, current limit
protection and power-on LED. The module
can be easy to interface via male or female
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
μA (typical) standby current. The output
switch includes cycle-by-cycle current
limiting, as well as thermal shutdown for full
protection under fault conditions.
