OP AMPSection
The integrated OP AMP is designed to offer Low Output Impedance, wideband, High input Impedance and wide
Common Mode Range. It can be readily used to implement protection features or a closed loop control. For this
purpose the OP AMP Output can be properly connected to R
fmin
pin to adjust the oscillation frequency.
Comparators
Two CMOS comparators are available to perform protection schemes. Short pulses (>= 200ns) on Comparators
Input are recognised. The EN1 input (active High), has a threshold of 0.6V (typical value) forces the L6598 in a
latched shut down state (e.g. LVG Low, HVG low, Oscillator stopped), as in the Under Voltage Conditions. Nor-
mal Operating conditions are resumed after a power-off power-on sequence. The EN2 input (active high), with
a threshold of 1.2V (typical value) restarts a Soft Start sequence (see Timing Diagrams). In addition the EN2
Comparator, when activated, removes a latched shutdown caused by EN1.
