GM2102

The GM2102 is a member of Gamma Microelectronics's family of white LED drivers.

The GM2102 is a fixed frequency step-up DC/DC converter designed to operate as a constant-current source. GM2102 is ideal for driving light emitting diodes (LEDs) whose light intensity is proportional to the current passing through them and not on the voltage across their terminals as it directly regulates the output current. The wide input voltage range allows the GM2102 to work from a variety of inputsources. A single external resistor sets LED current between 5mA and 40mA, which can then be easily adjusted using either a DC voltage or a PWM signal. In Shutdown mode, the LED's are disconnected from the output with the maximum quiescent current of 1A for the entire circuit.
