Product Summary

The rt8105gs is an advanced DC/DC synchronous buck PWM controller with several innovative functions for specific customer s ASIC only. The part features RichTek s innovative design and topology say “analogous current modefor current sensing and full functions for various applications including adjustable soft start, free-run and adjustable operation frequency and enable; the part is with design of 12V+12V boot strapped driver which is capable to drive up to 20Amp output current; moreover the part is with implementation of accuracy DCR current sensing topology. There are several specific features implemented and reserved for the specific customer’ s special applications including dual VCORE control mode including tracking and stand-alone mode, and output current indication. It is ideal for: (1)MB memory and chipset core power; (2)Middle-high graphic card GPU and memory core power; (3)General-purpose fields including server, NB, bare-bone and mini-system.
