Current Mode Pwm Controller - Advanced Analog Technology, Inc.

The AZ3842 AZ3843 AZ3844 AZ3845 are high performance fixed fre- quency 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. In addition, these ICs also feature accurate protection against over-temperature, over-current and maximal output power. The AZ3842 and AZ3844 have UVLO thresholds of 15.5V(on) and 10V(off); The corresponding thresholds for AZ3843 and AZ3845 are 8.4 V(on) and 7.8V(off). The AZ3842 and AZ3843 CAN operate approaching 100% duty cycle; AZ3844 and AZ3845 CAN operate from zero to 50% duty cycle. These ICs are available in 3 packages: SOIC-8, DIP-8 and SOIC-14.
