The RTC6659E is typically available in a QFN (Quad Flat No-leads) package, often in a 4x4 mm or 5x5 mm size with exposed thermal pads for heat dissipation. This compact, surface-mount package is common for power management ICs, offering efficient thermal performance and space-saving design. Exact dimensions and pin counts may vary, so check the datasheet for specifics.
