TD2786 Datasheet | Techcode

Description TD2786 is a 3A synchronous buck converter with integrated power MOSFETs. The TD2786 design with a current‐mode control scheme, can convert wide input voltage of 4.5V to 30V to the output voltage adjustable from 0.92V to 28V to provide excellent output voltage regulation. The TD2786 is equipped with an automatic PFM/PWM mode operation. At light load, the IC operates in the PFM mode to reduce the switching losses. At heavy load, the IC works in PWM mode. The TD2786 is also equipped with Power‐on‐reset, soft‐ start, and whole protections (over‐temperature, and current‐limit) into a single package. This device, available ESOP‐8, provides a very pact system solution external ponents and PCB area.
