Green Solution Technology GS92A3
The GS92A3 is small size chip with a relative constant on-time synchronous buck switching converter suitable for applications in notebook computers and other battery operated portable devices. The fast dynamic transient response means that buck converter applications based on GS92A3 will provide about 100ns-order response to load when output voltage falls down or rises up. The frequency will increase or decrease to meet the change in output load.| Part No. | GS92A3 |
