XL7045 Buck IC

XL7045 DC to DC Buck Converter IC

The XL7045 is a 100KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 0.3A 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 output short protection function happens, the operation frequency will be reduced from 100KHz to 15KHz. An internal compensation block is built in to minimize external component count.

The main advantage of using XL7045 step down DC to DC converter is its input voltage range which is from 12 volts to 80 volts.
