Inductance value is selected to make its ripple current 20-30% of the load current. A Schottky diode (D5) is usually used for better efficiency as long as the breakdown voltage can withstand the maximum output voltage. The forward current rating of the diode must be at least equal to the maximum LED current. Design Features 95% Efficiency 4.8V to 30V Input and up to 1.5A Output 1.4 MHz Switching & Small SOT23-6 Package PWM (0-100%, 0.1-10kHz) Dimming Thermal Shutdown & Short Circuit Protection For AC input, if a conventional step-down line transformer is used, a low cost IN4001can be used for D1-D4. However, if a high frequency electronic transformer is used, a Schottky diode such as SS14 should be used for high efficiency operation. For input and output capacitors, small size and low ESR ceramic capacitor is preferred. Operation and Application The bridge rectifier is for AC input only. The DC input is directly PC Board Layout Guidance connected to IN and ground. The ACT111A has an under- Place input capacitor (C1) to IN pin, inductor (L1) and diode voltage lockout (UVLO) at 4.0V with 250mV hysteresis. When (D5) to SW pin as close as possible to reduce the voltage ring- input voltage falls below 4.0V, SW stops switching. The device is ing at these pins. Place the current sense resistor (R2 ) close to activated as input voltage goes higher than 4.2V. FB pin. Minimize ground noise by connecting high current The LED output current is sensed by a resistor in series with the ground returns, the input capacitor ground lead, and the out- LED. The ACT111A precisely regulates the LED current by the put filter ground lead to a single point (star ground configura- internal EA and 0.1V reference. The average LED current is de- tion). There are two power loops in normal operation, one is termined by the equation: ILED =0.1V/RSENSE. formed when the SW is high and the high current flows The ACT111A allows dimming with a PWM signal at the DIM through input capacitor (C1), internal MOSFET, inductor(L1), pin. A signal level above 1.5V enables switching and turns LED LEDs, RSENSE(R2) to ground. The other loop is through inductor on. To turn off the LED current, the signal level has to be below (L1), LEDs, RSENSE(R2), ground to diode(D5). Make these loop 1.52V. The dimming signal frequency range is from 100Hz to areas as small as possible to minimize noise interaction. 10kHz.A 200kΩ resistor is needed to connect between FB pin RSENSE. A 100pF capacitor is recommended to connect from the FB pin to ground. 29 ACT111A High Efficiency, Low Cost HB LED Lighting Schematic ( VIN=12VDC or AC, 3x350mA LEDs ) PCB Top Layer Bill of Materials Ref.
