2.5, 11/2002 Switch Mode Power Supply with Multiple Linear Regulators and High Speed CAN Transceiver The 33394 is a multi output power supply integrated circuit with high speed CAN transceiver.

The IC incorporates a switching pre regulator operating over a wide input voltage range from +4.0V to +26.5V (with transients up to 45V).

The switching regulator has an internal 3.0A current limit and runs in both buck mode or boost mode to a
