Introduction

AI Translation

The XR76203, XR76205 and XR76208 are synchronous step-down regulators combining the controller, drivers, bootstrap diode and MOSFETs in a single package for point-of-load supplies. The XR76203, XR76205, and XR76208 have load current ratings of 3A, 5A and 8A respectively. A wide 5V to 40V input voltage range allows for single supply operation from industry standard 24V±10%, 18V - 36V, and rectified 18VAC and 24VAC rails. With a proprietary emulated current mode Constant On-Time (COT) control scheme, the XR76203, XR76205, and XR76208 provide extremely fast line and load transient response using ceramic output capacitors. They require no loop compensation, simplifying circuit implementation and reducing overall component count. The control loop also provides 0.07% load and 0.15% line regulation and maintains constant operating frequency. A selectable power saving mode allows the user to operate in discontinuous conduction mode (DCM) at light current loads, thereby significantly increasing the converter efficiency. A host of protection features, including over-current, over-temperature, short-circuit and UVLO, helps achieve safe operation under abnormal operating conditions. The XR76203, XR76205, and XR76208 are all available in a RoHS-compliant, green / halogen-free, space-saving QFN 5x5mm package.
