Package Information PACKAGE TYPE: 9 WLP Package Code W91F1+1 Outline Number 21-100234 Land Pattern Number Refer to Application Note 1891 THERMAL RESISTANCE, FOUR-LAYER BOARD Junction to Ambient ( ) 83.98C/W JA For the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages. Note that a +, , or - in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing pertains to the package regardless of RoHS status. Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial. Electrical Characteristics (V = 2.5V to 5.5V, T = -40C to +85C unless otherwise noted. Typical values are at V = +2.5V, T = +25C.)
