200KHZ, 1.5A PWM BUCK

DC/DC CONVERTER

DESCRIPTION

The UTC P1595 is a monolithic integrated circuit intended for the

use of a step-down DC/DC converter and it can drive a 1.5A load

without additional transistors.

The internal compensation makes feedback control having good

line and load regulation without external design. The external

shutdown function can be controlled by logic level and then enter the

standby mode.

The UTC P1595 features a guaranteed +3% tolerance on

output voltage under specified input voltage and output load

conditions. Thermal shutdown protection is designed to prevent over

temperature operating from damage while current limit protection is

against over current operating of the output switch. The switching

frequency will be reduced if current limit function occurs and feedback

switching frequency so it allows smaller sized filter components.

FEATURES

* Output Voltage In Adjustable Output Version.
