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.

MODEL: AEQ15AF48 SERIES JUNE 16, 2003 - REVISION 01 SHEET 7 OF 15 Technical Reference Notes AEQ15AF48 Series (Dual Output Quarter Brick - Baseplate) Basic Operation and Features INPUT UNDER VOLTAGE LOCKOUT To prevent any instability to the converter, which may affect the end system, the AEQ15 series have been designed to turn-on once VIN is in the voltage range of 34.5-36 VDC. Likewise, it has also been programmed to turn-off when VIN drops down to 30 – 32.5 VDC. OUTPUT VOLTAGE ADJUST/TRIM The converter comes with a TRIM pin (PIN 6), which is used to adjust both outputs simultaneously by as much as 90% to 110% of its set point. This is achieved by connecting an external resistor as described below. To INCREASE the output voltages, external Radj_up resistor should be connected between TRIM PIN (Pin6) and +Vo2 (Pin 4). Please refer to Equation (1) for the VO,adj and Radj_up relationship. Equation (1) where: %VO,adj = percent change in o/p voltage Figure 3. External Trim resistor setup to increase o/p. To DECREASE the output voltages, external Radj_down resistor should be connected between TRIM PIN (Pin 6) and O/P Return (Pin 5). Please refer to Equation (2) for the VO,adj and Radj_down relationship. Equation (2) Figure 4. External Trim resistor setup to decrease o/p. MODEL: AEQ15AF48 SERIES JUNE 16, 2003 - REVISION 01 SHEET 8 OF 15 Technical Reference Notes AEQ15AF48 Series (Dual Output Quarter Brick - Baseplate) Basic Operation and Features (continued) OUTPUT ENABLE The AEQ15 comes with an Enable pin (PIN 2) which is primarily used to turn ON/OFF the converter. Both a Positive (no part number suffix required) and Negative (suffix “N” required) Enable Logic option is being offered (see Part Numbering Scheme in Table 1). For Positive Enable, the converter is turned on when the Enable pin is at logic HIGH or left open. The unit turns off when the Enable pin is at logic LOW or directly connected to -VIN. 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. 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 converter will automatically recover once the fault is removed. OUTPUT 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 by going into a hiccup mode until the cause of the over current condition is removed. Note that in Figures 5 and 6, Channel 1 is 3.3V and Channel 2 is 5V. Figure 5. IO2 (5V) = OCP, IO1 (3V3) = 1A. Figure 6. IO2 (5V) = 1A, IO1 (3V3) = OCP. MODEL: AEQ15AF48 SERIES JUNE 16, 2003 - REVISION 01 SHEET 9 OF 15 Technical Reference Notes AEQ15AF48 Series (Dual Output Quarter Brick - Baseplate) Basic Operation and Features (continued) OVER TEMPERATURE PROTECTION (OTP) The Over Temperature Protection circuit will shutdown the converter once the sensed location reaches the OTP range. This feature prevents the unit from overheating and consequently going into thermal runaway, which may further damage the converter and the end system. Such overheating may be an effect of operation outside the given power thermal derating conditions. Restart is possible once the baseplate temperature drops to less than 105°C.

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.
