XT2401 PWM/PFM Automatic Controlled DC-DC Converters—Backlight Driver ■ General Description XT2401 series is a group of high efficiency synchronous-rectification type buck regulator using a constant frequency, current mode architecture. Automatic PWM/PFM mode operation increases efficiency and decreases output voltage ripple at light loads, further extending battery life. Switching frequency is internally set at 1.4MHz, allowing the use of small surface mount inductors and capacitors. 100% duty cycle provides low dropout operation.  Oscillation Frequency: 1.4MHz ■ Applications  LED driver ■ Package  SOT-23-5L ■ Features  High Efficiency: 92％  Output Current: 800mA  Shutdown Current: <1uA ■ Typical Application Circuit VIN C1 4.7uF Common GND VIN LX CE FB L 2.
