P1580
LINEAR INTEGRATED CIRCUIT
380KHz, 2.5A STEP-DOWN
SWITCHING REGULATOR
„ DESCRIPTION
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. An internal
1.222V reference voltage provides low output voltage down to 1.22V
for further applications. The over-current protection of controller
monitors the output current by using the voltage drop across a
current sensing resistor. Additional under voltage protection monitors
the voltage on FB pin for short-circuits protection.
The UTC P1580 provides fast transient response and requires
very few external devices for operation.
