NOTES:
1. Add “-T” suffix for tape and reel. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both
SnPb and Pb-free soldering operations). Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.

CLK_EN#
Open drain output to enable system PLL clock. It goes low 13 switching cycles after
V CORE is within 10% of V BOOT .

PGOOD
Power-Good open-drain output indicating when the regulator is able to supply
regulated voltage. Pull up externally with a 680 Ω resistor to VCCP or 1.9k Ω to 3.3V.

RBIAS
A resistor to GND sets internal current reference. A 147k Ω resistor sets the controller
for CPU core application and a 47k Ω resistor sets the controller for GPU core
application.
