XL2596-Adj, Adjustable voltage PWM Stepdown DC/DC Buck Converter SMD TO-263 IC

XL2596-Adj, Adjustable voltage PWM Stepdown DC/DC Buck Converter SMD TO-263 IC

The XL2596 is a 150 KHz fixed frequency PWM buck (step-down) DC/DC converter capable of driving a 3A load with high efficiency, low ripple and excellent line and load regulation. Requiring minimal external components, the controller is simple to operate and includes internal frequency compensation and a fixed frequency oscillator.

The PWM control circuit is capable of linear duty cycle adjustment from 0 to 100%. An activation function and an overcurrent protection function are integrated. When the second current limiting function occurs, the operating frequency is reduced from 150KHz to 50KHz. An internal compensation block is integrated to minimize the number of external components.
