Exar Corporation XR76208-Q
The XR76203-Q, XR76205-Q and XR76208-Q are synchronous stepdown regulators combining the controller, drivers, bootstrap diode and MOSFETs in a single package for point-of-load supplies well suited for automotive applications. With a proprietary emulated current mode Constant On-Time (COT) control scheme, the XR76203-Q, XR76205-Q and XR76208-Q 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.

GENERAL DESCRIPTION
Qualified per AEC-Q100, the XR76203-Q, XR76205-Q and XR76208-Q have load current ratings of 3A, 5A and 8A respectively. A wide 5.5V to 40V input voltage range allows for single supply operation from 12V battery systems required to withstand load dump, industry standard 24V ±10%, 18V-36V, and rectified 18VAC and 24VAC rails.
