General Description
The G5790/G5791 is a monolithic step-down switch
mode regulator with a built in internal power MOSFET. It
achieves 2A/3A continuous output current over a wide
input supply range with excellent load and line regulation.
Current mode operation provides fast transient response
and eases loop stabilization.
Also provide skip mode. When loading too light clock
skip several cycle proportional to load.
Fault condition protection includes cycle-by-cycle current
limiting, output short circuit protection and thermal
shutdown. In shutdown mode the regulator draws
32μA of supply current. Programmable soft-start overwrites
the internal soft-start for various requirement of
output power up ramp and minimizes the inrush supply
current at initial startup.
The G5790/G5791 requires a minimum number of
readily available standard external components. It is
available in a SOP-8, DIP-8 and SOP-8 (FD) package.
