Introduction

The HPS3512 is a high power, high-performance PC104 PSU that supplies +3.3V, +5V, and +12V outputs. The HPS3512 also includes a flash-based microcontroller that supplies advanced power management and an RS232 serial port. The HPS3512 is designed for low noise embedded computer systems, has a wide input range of 6-40V(>6:1) and is ideal for battery or unregulated input applications. The HPS3512 is specifically designed for vehicular applications and has heavy-duty transient suppressors (up to 18000W) that clamp the input voltage to safe levels while maintaining normal power supply operation.

The HPS3512 is a state-of-the-art Mosfet based design that provides outstanding line and load regulation with efficiencies up to 90 percent. Organic Semiconductor Capacitors (OSC-CON) and Polymerized Organic Semiconductor capacitors (POSCAP) provide filtering that reduces ripple noises below 20mV. The low noise design makes the HPS3512 ideal for use aboard aircraft or military applications or wherever EMI or RFI must be minimized. Constant frequency architecture controllers provide excellent line and load transient response on the +5VDC and +12VDC outputs.

The HPS3512 has advanced power supply management functions that allow timed on/off control of the HPS3512, notification of changes to main power and secondary power status. For example, the HPS3512 can be programmed to power off the outputs in 60 seconds, and then turn on again 12 hours later.

The HPS3512 size is 3.55 x 3.775 inches, which is the same size as the PC/104 standard and has the same mounting holes pattern as the PC/104 standard. However, the HPS3512 does not include the PC/104 bus connectors. All generated voltages are provided to a removable header. A removable plug allows the HPS3512 to be easily installed. The RS232 serial port is provided on a 2x5 row pin header.

The HPS3512 can be configured to meet almost any power supply and battery powered need for embedded applications, whether that is a simple +5V application, or providing power for backlighted LCD panels.
