Overview
CURRENT MODE PWM CONTROLLER General Description Features Data Sheet AP384XC 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 th...
