3 System Overview
The P60 PDU-200 (Power Distribution Unit) is a GomSpace daughterboard to be used with the P60
Dock. It contains 9 output channels with configurable voltage output.

3.1 Highlighted Features
P60 PDU-200 Module
- 9 switchable, latch-up, overcurrent protected outputs
- Outputs available in a high-current rated discreet connector
- Outputs are routed via P60 Dock to the PC104 stack
- 3 buck converters per module for regulated voltages below the battery voltage.
- Configurable output voltages per module of 3.3 V, 5 V or 8 V
o 12 V, 18 V, 24 V possible for one regulator and two channels.
- Protected 1 A - 2 A programmable current limit on outputs
- Current and voltage measurements on each output channel
- Detection and logging of overcurrent events
- Synchronized out-of-phase converters for low EMI operation
- Spread Spectrum Frequency Modulation
- Mass: 57 g with shield
Note that the total power conversion is limited by thermal considerations. Hence installation
hardware and operating voltages is indirectly a limiting factor – in general the higher voltage the
higher power.

3.2 Block Diagram
The PDU module contains 3 buck converters that can be connected to each of the 9 output
channels. HW configuration during production fixes each output to a specific converter and sets the
voltage of each converter. An output channel can also be configured to unregulated battery voltage.
All 9 outputs are available in the motherboard stack connector, and only 6 of the channels are
available in the TFM connector (together with a few communication channels).

5 Absolute Maximum Ratings
Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to
the P60. Exposure to absolute maximum rating conditions for extended periods may affect the
reliability.
