EK47 Evaluation Kit APPLICABLE PARTS (SOLD SEPARATELY) • PB63/PB64 Power Booster INTRODUCTION This easy-to-use kit provides a platform for the evaluation of the PB63/PB64 high voltage power boosters. The PB63/PB64 is designed most commonly in combination with a small signal, general purpose op amp. However, they can also be used without a driver amplifier. This kit can be used to analyze a multitude of standard or proprietary circuit configurations. Figure 1: PCB Layout 6.00” 5.25” www.apexanalog.com © Apex Microtechnology Inc.

This topology allows the user to evaluate each channel of the PB63/PB64 independently as a single ended driver or simultaneously operating in bridge mode. The circuit will accept a true differential input signal as well as a single ended input signal applied to either input. The voltage gain is approximately 46 Volts per Volt with the component values specified in the table. Please refer to the schematic diagram. R5 + R15 GAIN = ----------------------- + 1 R9 CAUTION Use the supplied thermal washers or thermal grease between the power amplifier and the heat sink.

Always use the heat sink and thermal washers included in this kit. Always use adequate power supply bypassing. Do not change connections while the circuit is powered. Initially set all power supplies to the minimum operating levels allowed in the device data sheet. Check for oscillations. Please refer to Application Note, AN01 for general operating considerations. ASSEMBLY 1. On the silk screen side of the evaluation board, insert and solder the MS06 mating socket in DUT holes 112. Be sure each one is fully seated. 2. Solder components for your circuit. Be sure to include proper bypassing, required compensation components and current limit resistors. See the op amp data sheet for help in selecting these components. 3. Place the TW07 thermal washer on the heat sink over the mounting hole for the DUT. Place a #6 screw through the mounting hole and thread a #6 nut onto the screw at the back of the heat sink. Do not tighten. Note that there are two sets of mounting holes on the HS20. Holes on one edge allow room between the DUT and evaluation board for the MS06 socket. The holes on the other edge are for direct through hole mounting of the DUT to the evaluation board. It is recommended that you use the MS06. 4. Mount the DUT to the HS20 by sliding under the head of the #6 screw and on top of the thermal washer. Tighten the nut to the specified 8 to 10 in-lbs. (0.9 to 1.3 N*m) do not over torque. 5. Install leads of the DUT into the MS06 on the evaluation board. Use #6 self-tapping screws to secure the evaluation board to the HS20 heatsink as shown in the assembly diagram (Figure 3). 4 EK47U Rev D EK47 Figure 3: Assembly Diagram #6-32 NUT MS06 SOCKET TW07 THERMAL WASHER AMPLIFIER #6-32 x 1/2 SCREW #6-32 x 3/8 SCREW SELF-TAPPING 2 PLACES #6 NYLON WASHER 2 PLACES #6-32 x 1 SPACER OPTIONAL NEED TECHNICAL HELP?
