General Description

The TG1484 is a monolithic synchronous buck regulator. The

device integrates 100mΩ MOSFETS that provide 3A

continuous load cur-rent over a wide operating input voltage of

4.75V to 23V. Current mode control provides fast transient

response and cycle-by-cycle cur-rent limit. An adjustable

soft-start prevents inrush current at turn-on. In shutdown mode,

the supply cur-rent drops below 1 μA. This device, available in

an 8-pin SOIC pack-age, provides a very compact system

solution with minimal reliance on external components.
