9-bump WLCSP USB-C controller for compact Type-C designs
The CYPD2703-09FNXIT is an Infineon EZ-PD™ CMG1 USB Type-C controller in a 9-bump WLCSP measuring 1.38x1.35 mm — small enough to tuck into a USB-C plug or a space-constrained portable device PCB. It handles the Type-C configuration channel (CC) negotiation and power delivery policy, communicating over I²C and USB interfaces to the system host.
The 9-WLCSP package has a 0.4 mm ball pitch typical for this bump count — the 1.38x1.35 mm body fits under a USB-C receptacle or alongside a battery connector on a two-layer board if the fan-out vias are tented. Surface-mount assembly with standard lead-free reflow profile; the WLCSP requires no underfill for consumer shock levels, though a corner-staking dot adds margin for drop-test compliance.
