NCP3065/NCP3066 Drive LED Circuit
ON SemiconductorNCP3065/NCP3066for multi-mode LED controller with integrated 1.5A switch can be configured to buck, boost, reverse (drop - boost), and single-ended primary inductance converter (SEPIC) a variety of topologies. NCP3065/NCP3066 input voltage range of 3.0 ~ 40V, low feedback voltage of 235mV, the operating frequency can be adjusted, up to 250kHz. NCP3065/NCP3066's other features include:-by-cycle current limiting, do not need to control-loop compensation can be ceramic output capacitor, analog and digital PWM dimming capability, and internal thermal shutdown occurrence of hysteresis. NCP3065/NCP3066 LED drive circuit as shown.
