General Description
The D2504A is a 150KHz fixed frequency PWM buck (step-down)
DC/DC converter, capable of driving a 2A load with high efficiency,
low ripple and excellent line and load regulation. Requiring a minimum
number of external components, the regulator is simple to use and
include internal frequency compensation and a fixed-frequency
oscillator.
The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%. An
enable function, an over current protection function is built inside. An internal compensation
