Boost Converter Block Diagram
Figure 7
shows the most important waveforms during operation; for low, medium and
high loads up to overload condition. The output transistor is switched off immediately if
the overcurrent comparator detects an overcurrent level at the power DMOS or if the
sense output switches to low induced by a
V
BOOST
undervoltage command.
The
TLE 6363
is also protected against several boost loop errors:
In case of a feedback interruption a pull up current source (
I
FB
typ. 0.4
←
A), integrated at
pin BOFB pulls the voltage at the feedback pin BOFB above the reference voltage. The
boost output is switched off by the high error voltage which controls the
PWM-Comparator at a zero duty cycle.
In the case of a resistive loop error caused by leakage currents to ground, the boost
output voltage would increase to very high values. In order to protect the
V
BOOST
input as
well as the external load against catastrophic failures, an overvoltage protection is
provided which switches the output transistor off as soon as the voltage at pin
V
BOOST
exceeds the internal fixed overvoltage threshold
V
BOOVOFF
= typ. 37 V.
