XR76208 - 3A/5A/8A Synchronous Step Down COT Regulator

Download the XR76208 datasheet PDF. This datasheet also covers the XR76203 variant, as both devices belong to the same 3a/5a/8a synchronous step down cot regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

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.

Key Features

  • including over-current, over-temperature, short-circuit and UVLO, helps achieve safe operation under abnormal operating conditions. The XR76203/5/8 are available in a RoHS-compliant, green/halogen-free space-saving QFN 5x5mm package.

XR76203/5/8 40V PowerBloxTM 3A/5A/8A Synchronous Step Down COT Regulator General Description 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.
