Avantics AX3842S
The AX3842 Series is high performance fixed frequency current mode controllers. These integrated circuits feature a trimmed oscillator for precise duty cycle control.DESCRIPTION
That is specifically designed for Off-Line and DC To DC converter applications offering the designer a costeffective solution with minimal external components. A temperature compensated reference, high gain error amplifier, current sensing compara-tor, and a high current totem pole output ideally suited for driving a power MOSFET. Also included are protective features consisting of input and reference undervoltage lockouts each with hysteresis, cycle-by-cycle current limiting, programmable output deadtime, and a latch for single pulse metering. 8-Lead Plastic DIP-8 Package Code: P● 8-Lead Plastic SO-8 Package Code: S
