CURRENT MODE PWM CONTROLLER General Description The AZ2842/3/4/5 are high performance fixed frequency current-mode PWM controller series. w w w 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 AZ2842 and AZ2844 have UVLO thresholds of 15.5V(on) and 10V(off); The corresponding thresholds for AZ2843 and AZ2845 are 8.4 V(on) and 7.8V(off).
