PWM CONTROL 3A STEP-DOWN CONVERTER
DESCRIPTION
The UTC P34563 consists of step-down switching regulator
with PWM control.
The UTC P34563 provides low-ripple power, high efficiency,
and excellent transient characteristics. The PWM control circuit is
able to the duty ratio linearly forms 0 up to 100%. With the
addition of an internal P-channel Power MOS, and a diode
connected externally, these ICs can function as step-down
switching regulators. They serve as ideal power supply units for
portable devices when coupled with the HSOP-8 package,
providing such outstanding features as low current consumption.
Since this converter can accommodate an input voltage up to 40V.
