RT9610C Rt9610CGQW 2Q= Marking 2Q IC

The RT9610C Rt9610CGQW 2Q= Marking 2Q IC MOSFET Driver IC is a high-efficiency dual synchronous buck driver designed to drive high- and low-side N-channel MOSFETs in step-down (buck) converter applications. It provides high current drive capability and fast switching performance, making it ideal for CPU VRMs, GPU power modules, and motherboard DC-DC converters.

The RT9610C features adaptive dead-time control, anti-shoot-through protection, and optimized timing for high-efficiency synchronous operation. It supports a wide input voltage range and includes an under-voltage lockout (UVLO) circuit for system safety.

Packaged in a compact QFN form factor, this IC is identified by marking code “2Q=” with common variations such as 2QH, 2QQ, 2QK, 2QX, 2QW, 2Q, 2Q8, 2QB — all belonging to the RT9610C family. It’s widely used in motherboards, graphic cards, and VRM power stages.
