1MHz, All-Ceramic, 2A PWM Buck DC/DC Converter

General Description
The AT1528 high-efficiency, DC/DC buck converter delivers up to 2A of output current. The device oper-ates from an input voltage of 2.5V to 6V and provides an output voltage from 0.8V to VIN, making the AT1528 ideal for on-board post-regulation applications.

The AT1528 operate at a fixed frequency of 1MHz with an efficiency of up to 94%. The high operating fre-quency minimizes the size of external components. Internal soft-start control circuitry reduces inrush cur-rent. Short-circuit and thermal-overload protections improve design reliability.

The AT1528 are available in a space-saving 8-pin SOP and MSOP package.
