The AP3842C/3C/4C/5C are high performance fixed
frequency current-mode PWM controller series.
These integrated circuits are optimized for off-line and
DC-DC converter applications with minimum external
components. They feature under-voltage lockout
(UVLO) circuit with low start-up current, trimmed
oscillator for precise duty cycle control, current sense
comparator providing maximum current limiting and a
totem pole output stage for increasing output current.
In addition, these ICs also feature accurate protection
against over-temperature, over-current and maximal
output power.
The AP3842C and AP3844C have UVLO thresholds
of 16V(on) and 10V(off); The corresponding thresholds
for AP3843C and AP3845C are 8.4 V(on) and
7.6V(off).
