The SG1845J-883B is a current mode PWM controller designed for off-line fixed frequency, current-mode switching power supplies. It operates with a low start-up current of less than 1mA and features pulse-by-pulse current limiting, under-voltage lockout, and automatic feed forward compensation. The device is optimized for driving power MOSFETs with a high-current totem-pole output and is capable of operating at frequencies up to 500kHz. It is specified for a military temperature range of -55¬8C to 125¬8C, making it suitable for demanding applications. The SG1845J-883B is available in a 14-pin ceramic dual inline package and meets MIL-STD-883 standards, ensuring reliability in critical environments.
