Its 100 kHz fixed switching frequency and 48% maximum duty cycle suit it for medium-power DC-DC stages where isolation is handled by a transformer or optocoupler. The operating temperature range of 0°C to 70°C covers commercial and industrial indoor environments. ## Automotive-grade qualification and lifecycle Listed under the Automotive, AEC-Q100 series, the TL3845P carries the qualification for automotive-grade IC reliability, including temperature cycling and ESD sensitivity testing per JEDEC. This makes it suitable for under-hood or cabin electronics that demand PPAP-level traceability. ## Package and board-fit for through-hole assembly The tube packaging suits manual assembly or low-volume pick-and-place with a tube feeder. The single-output transistor driver provides a positive output configuration with frequency control via an external RC network. No clock synchronization or synchronous rectification is integrated, so the designer manages external rectification and switching noise filtering.","metaTitle":"Texas Instruments TL3845P PWM Controller, 100kHz, 8-DIP","metaDescription":"Texas Instruments TL3845P PWM controller IC, 100kHz switching, 48% max duty, 7.6-30V supply, 0-70°C.

The TL3845P is a single-output controller in an 8-DIP package, while the UCC2806DWTR is a dual-output controller in a surface-mount SOIC package. The pinouts, supply voltage range, and output configuration differ significantly.
