To prevent burning out the driver, the output voltage must be 5.0VDC higher than the input voltage 2. Do NOT exceed the maximum power ratings on each model 3. With output ripple being rather low, it is recommended not to increase the additional output capacitor so s not to increase the delay while starting up under cool start conditions 4. This series offers protection in case the output is shorted. After the short occurs, thDe input current will be cut off and recovers when the short is removed 5. The reference value of under voltage protection (7.6V) means that under the condition of cool start and full discharge of output, the protection starts when input voltage is lower than 7.6V 6. Note: PWM dimming means PWM signals are converted into mimic analog voltage by internal circuits and then do the dimming. The advantage of this approach is to reduce the EMI Safety Specifications Parameters Standards NOTE: Designed to meet EN 55022 Class B, IEC/EN 60950-1 , UL8750, IEC/EN 61347-2-13 Pin Out Specifications Pin 1 2 3 4 5 6 Single +Vi DIM ON/OFF -Vi +LED -LED www.aimtec.com F 051e R12.A + DC Supply PWM/Analog Dimming Control Remote ON/OFF -DC Supply LED Anode connection LED Cathode connection Tel: +1 514 620 2722 2 of 7 Toll free: + 1 888 9 AIMTEC (924 6832) North America only Series AMLB-Z Up to 700mA | Step Up LED Driver Operating Temperature Free Air Convection AMLB-3615Z AMLB-3625Z (Vin:18V-36V) AMLB-3630Z (Vin:18V-36V) AMLB-3635Z (Vin: 18V-36V) Output Power (%) 100 80 AMLB-3650Z (Vin:18V-36V) AMLB-3625Z (Vin:9V-18V) AMLB-3630Z (Vin:9V-18V) 60 Safe Operating Area AMLB-3635Z (Vin:9V-18V) AMLB-3660Z (Vin:18V-36V) AMLB-3670Z (Vin:18V-36V) 40 AMLB-3650Z (Vin:9V-18V) AMLB-3660Z (Vin:9V-18V) AMLB-3670Z (Vin:9V-18V) 20 0 70 75 - 40 - 20 0 20 40 60 Ambient Temperature 85 80 100 ºC Dimensions Mechanical Tolerances Case tolerance ± 0.5mm or ± 0.02 inches Pin diameter 1.0 ± 0.05mm or 0.04 ± 0.002 inches Pin Pitch tolerance: ± 0.35 or ± 0.014 www.aimtec.com F 051e R12.A Tel: +1 514 620 2722 3 of 7 Toll free: + 1 888 9 AIMTEC (924 6832) North America only Series AMLB-Z Up to 700mA | Step Up LED Driver EN55022 Class B Filter Suggestion: Application circuit examples: +Vin +LED 1 +Vin 1st LED 5 AMLB-Z +LED 1 1 5 AMLB-Z 4 -Vin 6 2 DIM 3 PWM/Analog Dimming Control EN 1 4 -Vin Last LED 2 3 DIM -LED 6 PWM/Analog Dimming Control 1 1 1 1 1st LED EN Last LED -LED +Vin +LED 5 1 AMLB-Z 4 -Vin DIM AC In 6.5Vac to 25Vac 0.1uF optional 2 EN 3 ON SW OFF 1st LED 1 6 1 Last LED SW Vout ON 0V OFF normal -LED +Vin 100uF to + 330uF - +LED 1 5 1st LED 1 AMLB-Z 4 6 -Vin 2 AC In www.aimtec.com F 051e R12.A DIM PWM/Analog Dimming Control Tel: +1 514 620 2722 4 of 7 Last LED 3 1 EN -LED Toll free: + 1 888 9 AIMTEC (924 6832) North America only Series AMLB-Z Up to 700mA | Step Up LED Driver Under Voltage Protection +Vin +LED 1 1st LED 5 1 AMLB-Z 6 4 -Vin 2 EN 3 DIM Last LED 1 R1 -LED *R1 Value only supplies the reference R1 Under Voltage Protection X 7.6V 12K 10.8V 10K 11.6V 7.5K 13.0V 4.7K 16.5V 3.3K 21.0V 2.7K 24.1V 2.4K 26.2V 2.0K 29.8V 1.8K 32.4V Output Current Adjustment by External DC Control Voltage (VCTRL): +Vin +LED 5 1 0.4V-1.7V 2 DC DIM 4 -Vin +Vin 6 3 Last LED 1 EN GND 1st LED 1 AMLB-Z R1 -LED If Vin is between 9 VDC and 36 VDC it is recommended to use the circuit shown below R2 DIM R1 380K +5v 380K 30K 1 +Vin 1 AMLB-Z 2 VR DIM 200K 0V-1.7V -Vin 3 4 R1 +LED 5 DIM -Vin 4 1st LED 1 AMLB-Z 6 Last LED 3 EN 1 -LED 1 -LED 0 – 10VDC Vin R1 5V 4.7K 12V 18K 24V 43K 36V 62K 1M +Vin 1 0V-1.7V R2 1st LED 1 6 EN DIM 200K 2 TL431 +LED 5 VR +Vin 1 210K 5 1 2 DIM AMLB-Z -Vin 4 6 3 EN www.aimtec.com F 051e R12.A +LED 1st LED 1 -LED Tel: +1 514 620 2722 5 of 7 Toll free: + 1 888 9 AIMTEC (924 6832) North America only Series AMLB-Z Up to 700mA | Step Up LED Driver Output Current Adjustment by PWM Control: A Pulse Width Modulation (PWM) signal with a duty cycle DPWM can be applied to the DIM pin as shown below.
