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.
Latching Shutdown
The output overvoltage protection latch is activated by a high-
current pulse into the CONTROL pin. When set, the latch
turns off the
TOPSwitch
output. Activating the power-up
reset circuit by removing and restoring input power, or
momentarily pulling the CONTROL pin below the power-up
reset threshold resets the latch and allows
TOPSwitch
to
resume normal power supply operation. V
is regulated in
hysteretic mode when the power supply is latched off.
Over-Temperature 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). Activating the power-up reset circuit by
removing and restoring input power or momentarily pulling the
CONTROL pin below the power-up reset threshold resets the
latch and allows
TOPSwitch
to resume normal power supply
operation. V
is regulated in hysteretic mode when the power
supply is latched 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. Hysteretic operation occurs
during auto-restart and latched shutdown. 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.
