Short Description: Industry-standard STMicroelectronics / Texas Instruments UC3843BN (top marking code: UC3843BN) current-mode pulse width modulation (PWM) controller IC in a standard 8-pin DIP package. Specially designed for off-line flyback, boost, and DC-DC converter applications requiring minimal external components. Features a low UVLO threshold ($8.4\text{V}$ Turn-On / $7.6\text{V}$ Turn-Off) with up to $100\%$ duty cycle capability and a high-current totem-pole output stage capable of directly driving power MOSFET gates. Widely used in power supply adapters, desktop PC PSUs, battery charger controllers, industrial DC-DC converters, and auxiliary SMPS circuits. Essential replacement component for repairing blown power adapter boards, ATX power supply primary control stages, and DC-DC boost modules.
