1 / 6 page UNISONIC TECHNOLOGIES CO., LTD P3586 LINEAR INTEGRATED CIRCUIT www.unisonic.com.tw 1 of 6 Copyright © 2010 Unisonic Technologies Co., Ltd QW-R103-050.A 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. The controller’s OCP (Over current protection) circuit monitors the output current by using the voltage drop across the power MOSFET’s RDS saving the use of a current sensing resistor. Over current protection circuit also monitors the voltage on FB pin under short-circuit conditions. The UTC P3586 is generally applied in portable devices. For maximum flexibility in determining loop dynamic, this device is equipped with compensation pin. In addition, it is requiring less external components for operation due to its configuration.
