UNISONIC TECHNOLOGIES CO., LTD P3586 LINEAR INTEGRATED CIRCUIT PWM CONTROL 3A STEP-DOWN CONVERTER  DESCRIPTION The UTC P3586 is a fixed 1.2MHz frequency, voltage mode, PWM controller with an internal power MOSFET. It supplies 3A continuous output current over a wide input supply range with excellent load and line regulation. An internal reference voltage source provides low output voltage down to 0.8V for further applications. A PWM control circuit can provide 0~100% duty ratio. The reliability of UTC P3586 achieved by such protection circuits. An UVLO (Under voltage lock output) circuit monitors the VCC supply voltage to prevent wrong logic controls.
