(*) mounted on board
Soft-start
The IC provides an on-board 8ms soft-start, a quasi-monotonic ramp from 0V to 2.5V for the A
error amplifier reference voltage, in order to avoid high current peaks in the primary circuit and
output voltage overshoots at start-up. In fact, if this reference gets the nominal value as soon as
the power-up occurs, the A E/A will go out of regulation and tend to sink much more current, thus
forcing PWM to work with the maximum duty-cycle.
Bounce or
Latch-mode
This option allows setting either latched-mode or auto restart after 1 second delay in case of
undervoltage faults.
