The UCC1803J from Texas Instruments is a high-speed, low-power integrated circuit designed for off-line and DC-to-DC fixed frequency current-mode switching power supplies. It contains all necessary control and drive components, minimizing external part count.
Key electrical specifications include a typical starting supply current of 100 µA and a typical operating supply current of 500 µA. The device supports operation up to 1 MHz and provides a 1A totem-pole output. It also features internal soft start, internal fault soft start, and internal leading-edge blanking of the current-sense signal. The voltage reference has a tolerance of 1.5% and the response time from current-sense to gate drive output is typically 70 ns.
This controller is housed in an 8-pin CDIP package, suitable for through-hole mounting. It operates within a temperature range of -55°C to 125°C. The UCC1803J shares the same pinout as the UC3842 and UC3842A families, offering design flexibility.
Ideal for battery-operated systems, the UCC1803J family provides efficient power management solutions with minimal component requirements.
