UC3842B High Performance Current Mode PWM Controller IC – DIP-8 Package
The UC3842 is available in an 8-Pin mini-DIP the necessary features to implement off-line, fixed-frequency current-mode control schemes with minimal external parts count. This technique results
in improved line regulation, enhanced load response characteristics, and a simpler, easier to design control loop. Topological advantages include inherent pulse-by-pulse current limiting. Protection circuitry includes built-in under-voltage lock-out and current limiting. Other features include fully-latched operation, a 1% trimmed bandgap reference, and a start-up current less than 1mA. These devices feature a totem-pole output designed to source and sink high peak current from a capacitive load, such as the gate of a power MOSFET. Consistent with N-channel power devices, the output is low in the OFF-state.
