Quick Start Guide
The GS61004B-EVBCD EVB is designed to ease customer evaluation of the PE29102 Full-Bridge E-
HEMT Driver. This chapter will guide the user through the evaluation board overview, hardware
operation, test setup and test results.
Evaluation Board Overview
The GS61004B-EVBCD evaluation board contains:
•
Terminal Block connectors for power, BNC coaxial PWM input and Terminal Block audio output
ports
•
Test points, header pins and jumpers for performance verification
•
Output Filters included (Note that blocking capacitors are required if converting to two half
bridges)
•
Molex power connector for P1 DC input
The operating specifications of the evaluation board are as follows:
•
Maximum input operating voltage of 30V (Maximum voltage is limited to 30V based on
inductor selection. Maximum voltage can be increased to 60V using inductors with higher
voltage rating.)
•
Maximum output current of 12A continuous (default setting, adjustable)
•
Frequency of operation of 200 kHz — 400 kHz.
•
Minimum high-side output pulse width of 3 ns
•
Minimum low-side output pulse width of 3 ns
Note: *
Maximum load current depends on die temperature and is further subject to switching
frequency and operating voltage. Forced air cooling or heat sinking can increase current rating.
