General Information
It is not possible to use the TLE 6387 to generate output voltages much higher than 5V
by simply adding a voltage divider to the output and feeding back only a fraction of the
output voltage to pin 9 (FB). This is due to the OTA
EA and OCACM being internally
conected to each other. In fact, whenever the generated output voltagediffers from the
voltage sensed at pin 9 (FB), a large DC-offset is added to the internal current mode
signal, which cannot be compensated by OTA
CC and which consequently will result in a
clamped output voltage.
The maximum load current which can be supplied is limited either by the power
dissipation of the driven transistor, by it’s gate capacitance, by the voltage drop across
the ESR of the choking coil or by the resonant frequency of the output LC-filter. At short
circuit condition (also start up condition) the max. current is limited by the short circuit
comparator (see section 4) which turns off the NMOS according to the product RDSon
times load current. So the MOSFet and the inductance (max. current rating) have to be
chosen appropriate
The minimum load current which has to be supplied is basically determined by the
maximum input voltage V
IN and the minimum duty cycle of the TLE 6387. If the load
supplied is too small, the output voltage may exceed 5V. In order to cover the entire input
voltage range a minimum load of 50
is recommended.
