GS9238
Description
The GS9238 is small size chip with a relative constant on-time synchronous buck switching converter suitable for applications in notebook puters and other battery operated portable devices. Features include wide input voltage range, high efficiency and fast dynamic response The GS9238 has a unique power save mode, which can save battery power supply by decreasing frequency when load current falls down below preset critical current point.
