PWM CONTROL 3A STEP-DOWN CONVERTER

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.  FEATURES * Input voltage: 8V~40V * Oscillation frequency: 100KHz * Duty ratio: 0%~100% PWM control * Adjustable version output voltage range from VFB to 38V * Enable and auto restart function. * Short Circuit Protect (SCP). * Thermal Shutdown function / Internal OVP. * Built-in internal SW P-channel MOS.  ORDERING INFORMATION Ordering Number Lead Free Halogen Free P34563L-SH2-R P34563G-SH2-R Package HSOP-8 Packing Tape Reel  MARKING www.unisonic.com.tw Copyright © 2019 Unisonic Technologies Co., Ltd 1 of 4 QW-R103-074.G P34563  PIN CONFIGURATION LINEAR INTEGRATED CIRCUIT EN/CT 1 8 FB VSS 2 7 SENSE2 SW VGATE 3 6 SENSE1 VCC 4 5 SW  PIN DESCRIPTION PIN NO. 1 2 3 4 5 6 7 8 PIN NAME EN/CT VSS VGATE VCC SW SENSE1 SENSE2 F.
