AZ3843 (AZ3842 - AZ3845) CURRENT MODE PWM CONTROLLER

AZ3843 (AZ3842 - AZ3845) CURRENT MODE PWM CONTROLLER

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 oscill.
