Shutdown/Auto-restart
To minimize
TOPSwitch
power dissipation, the shutdown/
auto-restart circuit turns the power supply on and off at a duty
cycle of typically 5% if an out of regulation condition persists.
Loss of regulation interrupts the external current into the
CONTROL pin. V
regulation changes from shunt mode to the
hysteretic auto-restart mode described above. When the fault
condition is removed, the power supply output becomes
regulated, V
regulation returns to shunt mode, and normal
operation of the power supply resumes.
Hysteretic Overtemperature Protection
Temperature protection is provided by a precision analog
circuit that turns the output MOSFET off when the junction
temperature exceeds the thermal shutdown temperature
(typically 145
°
C). When the junction temperature cools past
the hysteresis temperature, normal operation resumes. V
is
regulated in hysteretic mode while the power supply is turned
off.
High-voltage Bias Current Source
This current source biases
TOPSwitch
from the DRAIN pin and
charges the CONTROL pin external capacitance (C
) during
start-up or hysteretic operation. The current source is switched
on and off with an effective duty cycle of approximately 35%.
This duty cycle is determined by the ratio of CONTROL pin
charge (I
) and discharge currents (I
and I
). This current
source is turned off during normal operation when the output
MOSFET is switching.
