UNISONIC TECHNOLOGIES CO., LTD P1583 LINEAR INTEGRATED CIRCUIT 380KHz, 2.5A STEP-DOWN SWITCHING REGULATOR  DESCRIPTION The UTC P1583 is a fixed 380kHz frequency, current mode, PWM controller. It achieves 2.5A continuous output current over a wide input supply range with excellent load and line regulation. Equipped with an external compensation pin, this device offers user flexibility in determining loop dynamic. The UTC P1583 integrates controls, monitoring and protection functions into a single 8-pin package to provide a low cost and perfect power solution. The device provides maximum 24V operating input voltage. An internal 1.245V reference provides low output voltage down to 1.245V for further applications.
