ICL8800/ICL8810/ICL8820: Burst mode advantage and why jitter function?
Community Translation: ICL8800/ICL8810/ICL8820: バーストモードの利点および何故ジッタ機能ですか？
The burst mode is an add-on feature in the ICL8810 and ICL8820 feature set. It extends the power range of the controller to allow very low loads and is not limited anymore by the minimum switching frequency of 23 kHz and its on-time. The burst mode enables a very low stand-by power (lower than 100 milliwatts) over input voltage range. This means that the smart lighting requirement (standby power lower than 500 milliwatts) is met and more power budget is left over for additional components like sensors and microcontrollers.
The built-in jitter function of the ICL8820 improves the EMI performance, supports the fulfillment of EMI requirements in DC operation and allows achieving EMI certification without additional circuitry.
