General Description
The G5657 is a monolithic step-down switch mode
regulator with a built in internal power MOSFET. It
achieves 3A continuous output current over a wide in-
put supply range with excellent load and line regulation.
Current mode operation provides fast transient re-
sponse ans eases loop stabilization.
Fault condition protection includes cycle-by-cycle cur-
rent limiting, output short circuit protection and thermal
shutdown. In shutdown mode the regulator draws 25µA
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 G5657 requires a minimum number of readily
available standard external components. It is available
in a SOP-8 (FD) package.
