General Description

FTD2786 is a 3A synchronous buck converter with integrated

power MOSFETs. The FAC2786 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 FAC2786 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 FAC2786 is also equipped with Power-on-reset, soft- start,

and whole protections (over-temperature, and current-limit)

into a single package.

This device, available SOP-8E provides a very compact

system solution external components and PCB area.
