■ General 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.
