com Advanced Analog Circuits Data Sheet AZ3842/3/4/5 Features · Robust VREF Line/Load Regulation Low Line Regulation : 4mV Low Load Regulation : 4mV High Stability of Reference Voltage over a Full Temperature Range: 0.
2mV/ oC Operating Frequency up to 500KHz High PWM Frequency Stability over a Full Temperature Range: 2.
5% High PWM Frequency Stability under a Full Supply Voltage Range: 0.
2% Accurate Over-temperature Protection with Hysteresis UVLO with Hysteresis CURRENT MODE PWM CONTROLLER General Description The AZ3842/3/4/5 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 for 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.
