BCT3210S

White LED Driver and Charge Pump DC/DC Converter

The BCT3210S is a constant frequency charge pump DC/DC converter used for white LED applications; it is capable of driving up to 100mA of load current. The LED brightness which is proportional to the forward current can be set by the external resistor at the pin “CS” of BCT3210S. A space saving design can be easily built by incorporating external SMT capacitors and resistors.
