Switching regulator Burst Mode control circuitry is provided for limiting
voltage overshoot at the output of a switching regulator operating in
power saving Burst Mode. The Burst Mode control circuitry may include
regulator load current sensing circuitry which may be operative to put
and maintain the regulator in the SLEEP state when the load current
amplitude is below a threshold. The control circuitry may also include
gated over-voltage comparator circuitry operative to reduce regulator
output overshoot and to eliminate erroneous deactivation of the regulator
switch circuitry when the regulator is not operating in Burst Mode. The
gated over-voltage circuitry may include a one-shot timer circuit.
