KP1315SPA

0-10v Linear Dimming Isolated PWM Dimming Chip

KP1315SPA is a high efficiency, quasi-resonant primary constant current LED driver controller that supports PWM dimming and 0-10V dimming with high precision and dimming depth, suitable for applications such as medium and high power isolated lighting power supply. The KP1315SPA has an integrated high voltage start circuit for fast start. 

At the same time, the chip works in the quasi-resonant control mode, which can greatly reduce the switching loss and improve the EMC while improving the efficiency. The KP1315SPA is also integrated with a high-precision constant current control algorithm, which can easily achieve high constant current accuracy, as well as excellent line voltage and load adjustment rate. The KP1315 integrates a variety of protection functions: VDD undervoltage protection (UVLO), overheat protection (OTP), cycle duration current protection (OCP), Short circuit protection (SCP), LED open circuit protection (OVP), etc.
