2MHz, High-Efficiency, Step-Up Converter for 5 to 6 White LEDs General Description The XR3081 is a current-mode and fixed frequency boost converter with an integrated N-FET to drive up to 5~6 white LEDs in series.
The series connection allows the LED current to be identical for uniform brightness.
Its low on resistance of N- FET and feedback voltage reduce power loss and achieve high efficiency.
Fast 1.
2MHz current-mode PWM operation is available for input and output capacitors and a small inductor while minimizing ripple on the input supply.
The OVP pin monitors the output volta...
