High Efficiency 90A Integrated Internal Current Sense Power Stage

SGM25890.pdf

The SGM25890 consists of an integrated driver, a control MOSFET, and a synchronous MOSFET. Due to the short distance connection between the internal driver and MOSFET, SGM25890 has better timing control and smaller switch node ringing while further improving its heat dissipation capability in terms of packaging. Appropriate driver and MOSFET size allocation enables SGM25890 to have better efficiency performance in low output voltage related applications such as CPU, GPU, and DDR Memory.

Compared to traditional DCR detection schemes, the internal MOSFET current detection scheme has higher current detection accuracy to help multiphase controllers obtain more accurate current information. The SGM25890 also has universal protection functions: OTP, OCP, HSS (high-side short detection), and VDRV under-voltage protection.

The SGM25890 supports a maximum switching frequency of 1.5MHz to ensure excellent dynamic performance when paired with multiphase controllers. Reasonable area allocation of both control MOSFET and synchronous MOSFET ensures optimal efficiency for SGM25890 in applications such as CPU, GPU, and DDR memory.

The SGM25890 is available in a Green TQFN-5×6-39L package.
