UNISONIC TECHNOLOGIES CO., LTD P1580 380KHz, 2.5A STEP-DOWN SWITCHING REGULATOR „ DESCRIPTION LINEAR INTEGRATED CIRCUIT The UTC P1580 is a current mode, PWM controller with 380kHz fixed frequency. It achieves 2.5A continuous output current over a wide input supply range with excellent load and line regulation. By using an external compensation pin, this device offers user flexibility in determining loop dynamic. The UTC P1580 integrates control, monitor and protection functions to provide a low cost and perfect power solution. The device provides 3.5 to 28V wide range operating input and high-efficiency up to 90%. An Under- Voltage-Lock-Output (UVLO) circuit monitors the supply voltage to prevent from wrong logic control.
