PV- 5127: Power supply module with UPS

Description

The Micronix PV-5127 is a high efficiency PC/104 power supply for embedded, vehicular and automotive systems applications. It will withstand extended temperatures and the shock and vibration of mobile equipment. Micronix PV-5127 has an input supply range of 18-35V (PV- 5127A: 10-35V), which is convenient for automotive and low-voltage applications. Intelligent back-up battery charger with temperature protection of your battery pack. Additionally, it has a built-in fan/heat control. Micronix PV-5127 has support for three ATX signals: PWR_GOOD, PS_ON, and +5V Standby.

Micronix PV-5127 supports sealed lead-acid batteries, and the Micronix PV-1075 PC/104 NiMH battery pack.

Block Diagram

PV-5127 is built around a high efficiency DC/DC converter that converts the incoming DC voltage to 5V/15A. This output is used for +5V Standby and is available at CN2 and CN10. A power switch is used for turning on/off the output voltages +5V and +12V under software control and by the safety shutdown function.

The mains power and backup battery are connected to KL2. The input selector circuit always selects the highest of the two voltages. If the mains voltage drops below the battery voltage, the backup battery immediately takes over.
