2018/10/09-ECL2401 PWM/PFM Automatic Controlled DC-DC Converters —Backlight Driver

General Description

ECL2401 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.
