General Description

The CM2500 is a current-mode step-down DC-DC converter that generates up to 2A output current at 380kHz switching frequency. The device utilizes advanced  BCD process  for operation with input voltage up to 20V consuming only 20μA in shutdown mode, the CM2500 is highly efficient with peak efficiency at 95% when in operation.

 Protection   features   include   cycle-by-cycle   current   limit, thermal shutdown, and frequency fold back at short circuit.

 The CM2500  is available in  SOP-8 package and requires very few external devices for operation.
