DEMONSTRATION BOARD TEST SETUP

This demonstration board test setup information details the test procedure for using the SiP11203 demonstration board and its associated host board. The demonstration board is plugged vertically into the host board. Only one orientation is possible for correct plugin. The input and output power leads and an optional enable lead are wired into the host board connectors as shown in Figure 1. A mechanical toggle switch is also available on the host board for manual enabling and disabling of the demonstration board.

FEATURES

• High efficiency, > 87 at full rated load current

• Delivers up to 15 amps of output current with minimal de-rating - no heat sink required

• Wide input voltage range: 35 V - 75 V, with 100 V 100 ms input voltage transient capability

• No minimum load requirement means no preload resistors required

• Remote sense for the output voltage compensates for output distribution drops

• On/Off control referenced to input side

• Input under-voltage lockout disables converter at low input voltage conditions

• Output short circuit protection protects converter and load from permanent damage and consequent hazardous conditions

• Output over-voltage protection protects load from damaging voltages

• Thermal shutdown protects converter from abnormal environmental conditions
