P34563

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.
