| Description: |
| The
DCDC5530-ADJ DC/DC Converter is highly efficient, buck converter with
low standby power drain. It is a three terminal device with over/under voltage
sensing and output current limiting via hall sensing, with a low dropout
voltage. Internal thermal sensing protects the unit when extreme over
temperature occurs. |
