    UNISONIC TECHNOLOGIES CO., LTD P34563 LINEAR INTEGRATED CIRCUIT 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.
