The Texas Instruments TL2845D is a versatile current-mode PWM controller designed for boost, flyback, and forward converter topologies. This device features a fixed-frequency architecture, operating at up to 500kHz, and offers a maximum duty cycle of 48%. It is suitable for positive output voltage regulation, including step-up and step-up/step-down configurations. The TL2845D includes frequency control for precise timing and a robust operating voltage range of 7.6V to 30V. Packaged in a 14-SOIC surface-mount format, it is engineered for applications in industrial power supplies, lighting, and consumer electronics. The output type is a transistor driver, and it operates as a single-phase device.
