General Description The XL7026 is a 150KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 0.6A 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%.
