QW-R103-055.C

200KHZ, 2A PWM BUCK

SWITCHING REGULATOR



DESCRIPTION

UTC UC34463 is a PWM control, step down DC to DC power

supply, fixed out 5V, with CC/CV mode and output line voltage

loss compensation function. External EN port can control

shutdown of the IC.

IC internal integration of various protection function, such as

SCP, OTP, OCP and so on. The highest working voltage is up to

40V.

The

built-in

compensation

simplifies

the

peripheral

applications.

The packages are available in a standard 8-lead SOP8.


