switched off the output capacitor is
discharged via pulse signal pwmpls. The
oscillator signal slogpwm sets the RS-flip-
flop. The gate drive circuit is switched on,
when capacitor voltage exceeds the
internal threshold of 0.4 V. This leads to a
linear ramp, which is created by the output
of the amplifier. Therefore duty cycle of
0 %
is
possible.
compensated through an internal compen-
sation network.
The transfer function of the amplifier can
be described as

Comparator (pwmcomp)
The comparator pwmcomp compares the
amplified current signal pwmrmp of the
CoolMOS with the reference signal pwmin.
Pwmin
is
created
optocoupler or external transistor and
gives the information of the feedback
circuitry. When the pwmrmp exceeds the
reference signal pwmin the comparator
switches the CoolMOS off.

Logic (logpwm)
The logic logpwm comprises a RS-flip-flop
and a NAND-gate. The NAND-gate
insures that CoolMOS transistor is only
switched on when sosta is on and pwmin
has exceeded minimum threshold and
pwmin
is
below
currentshutdown is off and tempshutdown
is off and tff sets the starting impulse.
CoolMOS transistor is switched off when
pwmrmp exceeds pwmin or duty cycle
exceeds 0.5 or pwmcs exceeds
I

or
silicium temperature exceeds
T
max
or uvlo
is going below threshold. The RS flip flop
ensures that with every frequency period
only one switch on can occur (double pulse
suppression).

Gate Drive (gtdrv)
Gtdrv is the driver circuit for the CoolMOS
and is optimized to minimize EMI
influences and to provide high circuit
efficiency. This is done by smoothing the
switch on slope when reaching the
CoolMOS threshold. Leading switch on
spike is minimized then. When CoolMOS
is witched off, the falling slope of the gate
driver is slowed down when reaching 2 V.
So an overshoot below ground can't occur.
Also gate drive circuit is designed to
eliminate cross conduction of the output
stage.
Current Shut Down (cssd)
Current shut down circuit switches the
CoolMOS immediately off when the sense
current is exceeding an internal threshold
of 100 mV at
