MaxLinear Unveils Jeju™ Custom PMIC, Engineered for Peak Efficiency with 1.6T Optical DSPs

MaxLinear introduced Jeju (MxL77904), a custom multiphase power management IC designed for 1.6T optical DSPs in AI infrastructure networks.
The device delivers up to 95% peak efficiency at low-voltage, high-current loads while saving up to 0.5W per DSP compared to conventional PMICs.
Jeju is purpose-built for 3nm & 4nm CMOS PAM4 DSPs to reduce thermal load, power consumption, & manufacturing costs in OSFP & QSFP-DD modules.
The MxL77904 utilizes a proprietary Constant On-Time architecture with dynamic voltage scaling to enable tight regulation with fewer external components.
Flexible phase configurations (up to 5A per phase) & low-noise power delivery support sensitive analog circuitry in next-generation optical modules.
The solution integrates over-voltage, under-voltage, over-current, short-circuit, & over-temperature protections within a compact 54-ball WLCSP package.
Jeju pairs with MaxLinear's Rushmore 1.6T PAM4 DSP to simplify integration & accelerate time to market for data center optics.
Samples of the Jeju PMIC are expected to be available to customers in February 2027.
