XR5162 _______________________________________________________________________________________________________ 1.1MHz, High-Efficiency, Step-Up Converter for 8 to 10 White LEDs or 3 *12 LED General Description The XR5162 is a current-mode and fixed frequency boost converter with an integrated N-FET to drive up to 8~10 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 1.1MHz 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 voltage and stops switching if exceeds the over-voltage threshold.
