200KHZ, 2A PWM BUCK SWITCHING REGULATOR
DESCRIPTION
UTC UC34463 is a PWM control, step down DC to DC power supply, fixed out 5V, with CA/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.
