LGATE
20
In synchronous buck mode, this pin is used to drive the lower side MOSFET to improve efficiency. A 5.1k or smaller value
resistor has to be added to connect LGATE to ground to avoid falsely turn-on of LGATE caused by coupling noise.
In non-synchronous buck when a diode is used as the bottom side power device, this pin should be connected to VCC through
a resistor (less than 5k) before VCC start-up to disable the low side driver (LGATE).
NC
7, 18
No connection pin. Connect these pins to SGND at quiet ground copper plane.
PAD
21
Bottom thermal pad. It is not connected to any electrical potential of the IC. In layout, it must be connected to PCB ground
copper plane with area as large as possible to effectively reduce the thermal impedance.

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.
3. For Moisture Sensitivity Level (MSL), please see device information page for ISL78206. For more information on MSL please see techbrief TB363.
