operation in continuous-conduction mode allow the use of tiny surface-mount inductors.
Output capacitor requirements are also reduced, minimizing PC board area and system
costs. The output voltage is preset at 5V (TLE6389-50) or 3.3V (TLE6389-33) and
adjustable for the TLE6389. Input voltages can be up to 60V.

1. For adjustable-output operation connect to an external voltage divider
between the output and GND (see the Setting the Output Voltage section).
2. Sense input for fixed 5V or 3.3V output operation. FB is internally
connected to an on-chip voltage divider.
