KP1601
KP1601 High-precision, deep dimming buck LED constant current driver KP1601 is a highly integrated buck constant current LED driver for LED backlight applications. The chip adopts a quasi-resonant operating mode and integrates accurate inductor current zero-crossing detection, achieving high efficiency while also obtaining good EMI performance. KP1601 integrates PWM dimming function, which can use PWM to analog dimming or direct PWM chopping dimming and combined dimming, and can achieve a wide dimming range of 0.01%~100%. The chip integrates high-precision current sampling technology and accurate current zero-crossing detection, combined with internal compensation, to obtain high-precision dimming linearity and consistency. KP1601 integrates complete protection functions to ensure safe and reliable operation of the system, such as: VDD undervoltage protection (UVLO), LED open circuit protection, LED short circuit protection, LED- to ground short circuit protection, inductor and diode short circuit protection, CS open circuit and CS short circuit to Drain protection, cycle-by-cycle current limit (OCP), overtemperature protection (OTP), leading edge blanking (LEB), etc. Main Features • PWM to analog and PWM chopping combined dimming • 0.01%~100% wide dimming range • Low standby current 35μA • Quasi-resonant mode high efficiency operation • Accurate inductor current zero-crossing detection • ±2% constant current accuracy @100% current • Soft start and zero-current turn-on improve EMI • Package type SOP-8 • Internal protection functions: • LED open circuit protection • LED short circuit and LED- to GND short circuit protection • Inductor and diode short circuit protection • CS open circuit protection • Drain to CS short circuit protection • VDD undervoltage protection (UVLO) • Cycle-by-cycle current limit (OCP) • Input undervoltage protection • Leading edge blanking (LEB) • Overtemperature protection (OTP)
