���������������������������� ���� � � � � � � � � � � � � � � � �������������������������������������������������������������� INTRODUCTION ASSEMBLY This easy-to-use kit provides a platform for the evaluation of the PB51 high voltage power boosters. The PB51 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. 1. On the silk screen side of the evaluation board, insert and solder the MS06 mating socket in DUT holes 1-12. Be sure each one is fully seated. 2. Solder components for your circuit. Be sure to incude proper bypassing, required compensaton 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. (.9 to .13 N*M) do not over torque. 5. Install leads of the DUT into the 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 (Figure1). CAUTION Use the supplied thermal washers or thermal grease between the power amplifier and the heat sink.
