The UC1842J from Texas Instruments is a Current Mode PWM Controller, part of the UCx84x series. It is optimized for use in off-line and DC-to-DC converters, requiring a minimal number of external components for implementation.
Key electrical features include operation up to 500kHz, a low start-up current of less than 1mA, and pulse-by-pulse current limiting. The device also incorporates an undervoltage lockout with hysteresis and a high-current totem-pole output stage designed for driving N-channel MOSFETs.
This controller operates within a temperature range of -55 to 125°C. It is housed in an 8-pin CDIP (JG) package and is suitable for through-hole mounting. The UC1842J is noted as not recommended for new designs.
Applications for this controller include various power supply designs where fixed-frequency current-mode control is desired.
