4、 Application Design Guidelines
4.1 Design scheme for communication power supply
Under the condition of 220V/50Hz AC power, the relationship between the capacitance C of capacitor C1 and the total current ILED can be approximated as: C=14.5× ILED。 its
In the middle, the unit of C isμ F, and the unit of ILED is A. When the total voltage drop of LED chips between different OUT ports is different, for example, although each OUT port
String 3 LED beads, but some ports string red LED, some ports string green LED, and some ports string blue LED, then string the red LED
The total voltage drop of the LED beads in the channel is relatively low. This channel should be connected in series with an appropriate resistor, otherwise it may cause abnormal pattern display due to insufficient driving of the resistor capacitor circuit.
If the total voltage drop of the LED beads in each channel of OUT0-OUT15 is V0-V15, and Vmax is the maximum value among them, then the OUTn channel should be connected in series with a resistance meter
The calculation formula is:
Rn=(Vmax- Vn)/Iled，
Iled=16mA.
For AC220V input applications, CXLE87188 supports resistance capacitance voltage reduction power supply solutions:
4.1.1 Selection of key components：
• Current limiting capacitor C1：0.5μF-1μ F， Determine based on the total LED current
• Discharge resistor R1：100KΩ -510KΩ
• Voltage regulator capacitor C2：100μF-220μ F
• VDD stabilizing resistor R3Calculated and determined based on the supply voltage
4.1.2 Current calculation formula：
The relationship between C1 capacity and total current under 220V/50Hz conditions: C=14.5× I_LED
Among them, C unitμ F, I2 LED unit A
4.2. Design scheme for DC power supply
Attention: 1. Component parameters should be configured based on specific LED lamp performance parameters and the number of LED beads used;
2. The arrangement order of light beads must be OUT0‐ OUT15， Suggest connecting one LED bead in series to each OUT port.
The current range that flows through the internal voltage regulator of VDD during normal operation of the chip is 1.0mA to 15mA. The formula for calculating the resistance value of R3 voltage regulator resistor is:
R3=(VLED-VDD)/Idd。 Assuming that the current Idd flowing through VDD is 10mA and the voltage regulation value VDD is 5.5V, the power supply voltage is different
The resistance values of R3 under the given conditions are shown in the table below:
FIN directly samples 220V AC mains power for the synchronous signal input of the chip through the sampling resistor R4. FIN is equipped with a voltage clamp circuit internally,
The FIN pin voltage can be clamped at around 6V, the FIN input current is recommended to be controlled between 2mA and 5mA, and the sampling resistor resistance is recommended to be between 100K and 50K
The smaller the resistance value of R4 selected, the greater the power consumption.
Due to the constant current output of the chip's OUT port, a certain voltage needs to be applied to the port in order to enter the constant current area. So in order to ensure the OUT port of the chip
When operating in a constant current state and considering chip power consumption, the voltage applied to the OUT port should be maintained at around 2V and should not exceed 6V
When, a resistor should be connected in series on the lamp bead, and the formula for calculating the resistance value is:
R=(VLED-nVled-2)/Iled，
Where Iled=16mA, nVled is the product of the number of LED beads n at the port and the voltage drop Vled of a single LED lamp.
For DC5V-24V input applications:
Resistance calculation formula：
• VDD current limiting resistor：R3 = (V_LED - V_DD) / I_DD
• LED series resistor：R = (V_max - V_n) / I_LED
4.3. Typical Configuration Example：
| power supply voltage | Recommended R3 resistance value |
|---|---|
| 5V | 0Ω (Direct connection) |
| 6V | 500Ω |
| 9V | 350Ω |
| 12V | 650Ω |
| 24V | 1.8KΩ |
4.4. Multi chip synchronization scheme
CXLE87188 supports multi chip synchronous operation to ensure consistent performance of large lighting devices
4.4.1 connection method：
• Connect FOUT output to FIN input of lower level chip
• Recommend star connections instead of cascading to reduce signal delay
• The synchronous signal line should be as short as possible to reduce noise interference
4.4.2 Synchronization advantage：
• Ensure that all chip pattern changes are completely synchronized
• Suitable for large-scale decorative lighting projects
• Simplify system control and debugging
4.4.3. Chip self synchronization
In the suspended state of FIN, the pattern changes are controlled internally by the chip. Due to process deviations, the frequency of PWM changes in the chip output may vary
Due to differences, the outputs of multiple chips may not be synchronized. At this point, the FOUT output signal of the chip can be used as the synchronization signal input for other chips,
Realize self synchronization of chip pattern changes. In this case, it is not recommended to use cascading synchronization. Instead, the following connection method can be used to achieve self synchronization
Step:
Explanation: In the connection method shown in the above figure, as the number of connected chips and the distance between chips increase, it will cause the FOUT pin of chip 1 to
The wire length of the FIN pin of each IC will also increase accordingly, which will inevitably lead to an increase in noise superimposed on the synchronization frequency. Therefore, it is recommended to follow the
The actual need is to choose the length of the connecting wire under different interference environments. The shorter the wire length, the better, while meeting the requirements.
Attention: When using a resistive capacitive buck circuit, the following precautions should be taken:
1. The circuit is not isolated from 220V AC high voltage, please pay attention to safety and strictly prevent electric shock;
2. The current limiting capacitor C1 should be connected to the live wire, with a sufficient withstand voltage (above 400V), and a discharge resistor R1 should be added;
3. Pay attention to the power consumption of the voltage regulator diode and prohibit its use when the voltage regulator diode is open circuit;
4. It is strictly prohibited to open the circuit and power on.
