Low-cost single layer PCB with very good EMC performance
Operation and Application
Higher output inductance reduces the inductor peak-to-peak
current at the expense of higher larger core size and inductance DCR value. Usually, an optimum inductance value is
selected to make its peak-to-peak current 20%-40% of the
maximum load current. The Schottky diode must have current
rating higher than the maximum output current and the reverse voltage rating higher than the maximum input voltage.
Output capacitor is selected to keep the peak-to-peak voltage
ripple under required value and also meet the load transient
requirements. Usually, the combination of low ESR capacitors
ACT4501 is a step-down DC-DC converter with wide input
and tantalum or electrolytic types are used. In this application,
voltage range and high efficiency dedicated to 5V/1A smart
220uF electrolytic capacitor is connected in parallel with a
phone micro car chargers. The ACT4501 is internally optimized
small 2.2μF ceramic capacitor to achieve small output voltage
for good EMC performance and it passed radiated EMI test
ripple and meet the requirements of input and load dynamic
even on low-cost single layer PCBs without adding any EMC
response.

Key Component Selection
An inductor with RMS rating greater than load current and its
saturation current at least 30% higher should be used. 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

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-

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

areas as small as possible to minimize noise interaction.
