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 ponents. They feature under-voltage lockout (UVLO) circuit with low start-up current, trimmed oscillator for precise duty cycle control, current sense parator 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).
- Low Start-up Current: 50μA
- Robust VREF Line/Load Regulation
Low Line Regulation : 4m V Low Load Regulation : 4m V
- High Stability of Reference Voltage over a Full Temperature...
