The UC2845D from Texas Instruments is a single-ended, current-mode PWM controller operating up to 500kHz. It is optimized for off-line and DC-to-DC converter applications, requiring a minimal number of external components.
Key electrical specifications include an operating voltage range of 12V to 28V and a maximum duty cycle of 48%. The device offers features such as pulse-by-pulse current limiting, undervoltage lockout with hysteresis, and a high-current totem-pole output. It supports various topologies including Boost, Buck, Flyback, and Forward.
Packaged in a 14-SOIC (0.154", 3.90mm Width) surface-mount case, the UC2845D operates within a temperature range of -40°C to 85°C. Its design facilitates enhanced load-response characteristics and includes an internally trimmed bandgap reference.
