DESCRIPTION
         LN2401 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.

FEATURES
         High efficiency: 92％
         Output current: 800mA
         Shutdown current: <1uA
         Oscillation frequency: 1.4MHz

APPLICATIONS
         LED driver
