HPSP-XYZ: Triple Programmable Output 240W SFF Power Supply

Overview

Smart SFF Power Supply With Triple Programmable Outputs & Dual Inputs

The HPSP is the product family name of the power supply platform HPSP-x-y-z. The “x” suffix defines the OUT1 voltage, “y” suffix the OUT2 voltage and “z” the OUT3 voltage. In addition to the three main outputs the HPSP also provides a 5VSBY 1A output.

The HPSP is a high power, high performance DC-to-DC converter that supplies three outputs programmable that are
programmable up to 24V output and supports an ultra wide input range of 6-50V. The HPSP has two power inputs protected
with heavy-duty transient surge stoppers that clamps the input voltage to safe levels. The HPSP is ideal for battery and
unregulated input applications. The HPSP uses a flash based microcontroller to supply advanced power management that
monitors and controls the operation of the HPSP through a RS232 serial port.

The HPSP is a state-of-the-art Mosfet based design that provides outstanding line and load regulation and high efficiency. The
low noise design makes the HPSP ideal for use aboard aircraft or military applications or wherever EMI or RFI must be
minimized.

The HPSP advanced power management functions provide timed on/off control of the HPSP, notification of changes to main
power and secondary power status.

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

ATX Compatibility

The HPSP can be configured to be signal compatible to an ATX power supply (The HPSP does not provide -5V, -12V that
standard ATX supplies include but the three outputs can be programmed to provide the standard 3.3V, 5V and 12V).
