~The CN4215 is a universal purpose linear LED driver. The operating voltage as wide as 30V is well suited for all kinds of applications. Separated VDD can be easily configured for high voltage input.
 
 The CN4215 only need one current setting resistor. No capacitors are required. With a strong internal power transistor and 200mV low CS voltage, CN4215 can drive up to 150mA current with only 350mV total dropout. Careful design and fine trimming keeps current accuracy within ±5%.

PWM dimming can be as high as 1MHz, while still holding good dimming linearity. With a proprietary design, CN4215 is also compatible with simple two wire switched dimming up to 100KHz frequency. OTP function prevents CN4215 from extreme conditions.

CN4215 is available in package SOT23-5

Payment Terms︰ TT
