3V Fixed 160KHz Switching Frequency Maximum 3A Output Current Capability Internal Optimize Power MOSFET Excellent line and load regulation High efficiency up to 92% TTL shutdown capability EN pin with hysteresis function With output constant current loop Built in Constant Voltage (CV) Loop Built in Constant Current (CC) Loop Built in thermal shutdown function Built in output short protection SOP8-EP package XL2006 General Description The XL2006 is a 160 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 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 block is built in to minimize external b€component count.
