protection is reset. The latch is reset as soon as V CC drops below 4.5 V (typical value)
(this only occurs when the mains has been disconnected). The internal
For the TEA1530T the IC always enters the latched mode protection independent of the
voltage on pin CTRL.
A voltage higher than 3 V on pin PROTECT will always latch the IC. This is independent of
the state of the IC.
7.12 OverTemperature Protection (OTP)
The IC provides accurate OTP. The IC stops switching when the junction temperature
exceeds the thermal shutdown temperature. When V CC drops to V th(UVLO) , capacitor C VCC
is recharged to the V startup level, however, switching will not restart. Subsequently, V CC will
drop again to V th(UVLO) .
Operation only recommences when V CC drops below a level of about 4.5 V, typically when
the mains voltage is disconnected for a short period.
7.13 Soft start-up (pin SENSE)
To prevent transformer rattle at start-up or during hiccup, the transformer peak current is
slowly increased by the soft start function. This can be achieved by inserting a resistor
and a capacitor between pin SENSE (pin 5) and sense resistor R sense . An internal current
source charges the capacitor to V SENSE = I startup(soft) × R ss (about 0.5 V maximum).
The start level and the time constant of the increasing primary current level can be
adjusted externally by changing the values of R ss and C ss .
V sense ( max ) – ( I startup(soft) × R ss )
I DM = --------------------------------------------------------------------------------
τ = R ss × C ss
The charging current I startup(soft) will ?ow as long as the voltage on pin SENSE is
below approximately 0.5 V. If the voltage on pin SENSE exceeds 0.5 V, the soft start
current source will start limiting current I startup(soft) . At V startup , the I startup(soft) current source
Since the soft start current I startup(soft) is supplied from pin DRAIN, the R ss value will not
affect V CC current during start-up.
