Features include very wide input voltage range, high efficiency and a fast dynamic response with internal fast response scheme. The GS92A5 have a unique power save mode, which can save battery power supply by decreasing frequency when load current falls down below preset critical current point. The fast dynamic transient response means that buck converter applications based on GS92A5 will provide about 100ns-order response to load when output ...
