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.
