High voltage drive SN3355 for LED disinfection lamp
High-voltage drive SN3355 for LED sterilizing lamps is an agent in stock and long-term supply. Welcome to inquire!
SN3355 is a step-down inductor current continuous mode driver chip, suitable for applications where the power supply voltage is higher than the voltage required by one or a string of LEDs. The chip has an input voltage range of 6V to 40V and an output current of up to 1A. SN3355 integrates power tube inside, adopts high current detection, and can set the average working current through external resistor RS. The output current can also be set by adding a control signal to the ADJ pin. When the ADJ pin voltage is lower than 0.2V, the chip will shut down and enter a low power consumption mode. The chip is packaged in SOT89-5 and can work at an ambient temperature of minus 40 degrees to plus 105 degrees.
SN3355 features:
Output current up to 1A
High efficiency (up to 97%)
Operating voltage range: 6V-40V
Integrated 40V power tube inside the chip
