Functional description
The TLE6387 DC-DC switching controllers are used to built up buck (or step down)
converter circuits for loads higher 1A with efficiencies higher than 80%. The device
combines the regulation loop for a buck converter topology with an output voltage
supervision module that generates a reset signal in case of over- or undervoltage at the
output of the step-down converter. The special observer-based adaptive current mode
control scheme requires neither external compensation in terms of an RC-network nor a
current sense resistor for proper operation of the buck circuit. These controllers drive an
external N-channel MOSFET, allowing design flexibility for different applications by
choosing the appropriate switching transistor. The high switching frequency of 400kHz
