ALQ15XX48X Series
(Open Frame Dual Output Quarter Brick)
MODEL: ALQ15 SERIES
SHEET 9 OF 18
OCTOBER 4, 2002 - REVISION A1
Basic Operation and Features
INPUT UNDER VOLTAGE LOCKOUT
To prevent any instability to the converter that may affect and consequently damage the end system, the ALQ15 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 32-33.5 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 RTRIM-UP resistor should be connected between TRIM PIN (Pin6) and RTN PIN
(Pin 5). Please refer to Figure 3 for the resistor configuration and Table 1 for the required resistor value in attaining the desired
output adjustment
To DECREASE the output voltages, external RTRIM-DOWN resistor should be connected between TRIM PIN (Pin 6) and VOUT1
(Pin 7). Please refer to Figure 4 for the resistor configuration and Table 1 for the required resistor value in attaining the desired
output adjustment.
