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

General Description
The  AT1526  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 AT1526 ideal for on-board post-regulation applications.

The AT1526 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 AT1526 are available in a space-saving 8-pin SO package.
