LT3783 boost configuration driving LED circuit diagram
Source: InternetPublisher:偷熊计划 Keywords: LED circuit boost type circuit diagram Updated: 2020/04/29
This circuit is a boost configuration using the LTC3783 , and the input voltage (9~18V) is boosted to the 30~54V voltage required by the LED string. The LED string can include 12 colored 700mA LEDs connected in series , providing a total of up to 38W of drive power. When the input voltage is 18V and the LED string voltage is 54V, the power efficiency achieved by this circuit can exceed 95%. Regardless of the circuit components used, this high efficiency can suppress the temperature rise below 25°C.
