FIGURE 26-CURRENT WAVEFORM SPIKE
SUPPRESSION
FIGURE 27-MOSFET PARASITIC OSCILLATIONS
The addition of RC filter will eliminate instability caused
by the leading edge splik on the current waveform.
FIGURE 28-BIPOLAR TRANSISTOR DRIVE
FIGURE 29-ISOLATED MOSFET DRIVE
The totem-pole output can furnish negative base current for
enhanced transistor turn-off,with the additions of capacitor C1.
FIGURE 30-LATCHED SHUTDOWN
FIGURE 31-ERROR AMPLIFIER COMPENSATION
The MCR101 SCR must be selected for a holding of less than 0.5mA at TA
(min).The simple two transistor circuit can be used in place of the SCR as
shown.All resistors are 10K.
Error Amp compensation circuit for stabilizing any currentmode topology
except for boost and flyback converters operating with continuous inductor
current.
