1MHz, All-Ceramic, 3.2A PWM Buck DC/DC Converter

General Description
The AT1530 high-efficiency, DC/DC buck converter delivers up to 3.2A 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 AT1530 ideal for on-board post-regulation applications.

The AT1530 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. Output under-voltage lockout, short-circuit and over-temperature protections improve design reliabil-ity.

The AT1530 are available in a space-saving SOP-8 and TDFN3X3-8 package.
