Scope measurement should be made using a BNC probe socket positioned about 76mm (3 in.) away from the module's output terminals. The ext. capacitors should be placed between the BNC socket and the module's output terminals, with a minimum distance of 51mm (2in.) from the latter. Figure 2.

Likewise, it has also been programmed to turn-off when VIN drops down to 17 - 18VDC. OUTPUT VOLTAGE ADJUST/TRIM Each channel/ output comes with a Trim pin (Pin 10 for VO1 and Pin 7 for VO2 ). This can be used to used to adjust the outputs up and down per the given trim range in the previous section. This is achieved by connecting an external resistor as described below. Output voltage adjustment is accomplished by connecting an external resistor between the Trim Pin and either the +VO or -VO Pins. With an external resistor, RTRIM between the Trim Pin and +VO Pin the output voltage increases. With RTRIM connected between the Trim Pin and -VO Pin the output voltage decreases. See Figure 3. The following equation determines the required external resistor value to obtain an adjusted output voltage: RTRIM = (G - ( H * VO,Adj)) / (V O,Adj - K ) Where: VO, ADJ = is the desired output voltage (e.g. 5.2 V = 5V * +4%) Trim Output Voltage UP (RTRIM connect to V+) Model Output G 036H 5/3.3 5 129980.1 036H 5/3.3 3.3 12194.5 H 10220 2000 K 5 3.3 Trim Output Voltage DOWN (RTRIM connect to V-) Model Output G 036H 5/3.3 5 25578.4 036H 5/3.3 3.3 3301.2 H 10220 2000 K 5 3.3 OUTPUT OVER VOLTAGE PROTECTION (OVP) The Over Voltage Protection circuit will shut down the entire converter if any of the two output voltages exceeds the OVP threshold limits. The output will remain latched until the OVP fault is removed and the input voltage is recycled MODEL: AA60A-036L-050D033H SERIES OCTOBER 10, 2002 - REVISION A SHEET 7 OF 12 Technical Reference Notes AA60A-036L-050D033H Series (5V / 3V3 Dual Output Half Brick) Basic Operation and Features (continued) OUTPUT ENABLE The AA60A comes with an Enable pin (PIN 3), which is primarily used to turn ON/OFF the converter. Both a Positive (no part number suffix required) and a Negative (suffix "N" required) Enable Logic option is being offered For Positive Enable, the converter is turned on when the Enable pin is at logic HIGH or le ft open. The unit turns off when the Enable pin is at logic LOW. On the other hand, the Negative Enable version turns on when the Enable pin is at logic LOW or directly connected to -VIN. The unit turns off when the Enable pin is at Logic HIGH. OVER CURRENT PROTECTION (OCP) The Over Current Protection circuit will shutdown the converter if any of the load current of either output reaches the OCP threshold limits. The unit will automatically recover once the over current condition is removed.

When wave soldering, the converter pins should be preheated for 20-30 seconds at 110?C and wave soldered at 260?C for less than 10 seconds. When hand soldering, the iron temperature should be maintained at 425?C and applied to the converter pins for less than 5 seconds. Longer exposure can cause internal damage to the converter. Cleaning can be performed with cleaning solvent IPA or with water.
