Isao Yamamoto, Kyoichiro Araki, Noboru Kagemoto: Boost controller capable of step-up ratio control. Rohm, Cantor Colburn, December 11, 2007: US07307385 (8 worldwide citation)

A charge pump circuit boosts a voltage of a battery so as to generate a drive voltage for an LED. A constant current circuit generates a constant current to feed through the LED. A monitoring circuit monitors a cathode potential of the LED, i.e., a voltage across the constant current circuit. A cont ...
