XL1509 General Description
The XL1509 is a 150 KHz 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.
When second current limit function happens, the operation frequency will be reduced from 150KHz to 50KHz.
