DESCRIPTION
17
PROG2 Programming pin for PWM/PFM mode, temperature compensation and serial bus (SMBus/PMBus/I²C) address.
18
PROG1 Programming pin for boot-up voltage.
19
GND Return current path for the LGATE MOSFET driver. Connect directly to system ground plane.
20
LGATE Low-side MOSFET gate driver output. Connect to the gate terminal of the low-side MOSFET of the converter.
21
PHASE Return path for the UGATE high-side MOSFET driver, and zero inductor current detector input for diode emulation.
22
UGATE High-side MOSFET gate driver output. Connect to the gate terminal of the high-side MOSFET of the converter.
23
BOOT Positive input supply for the UGATE high-side MOSFET gate driver. Connect an MLCC (0.22µF, X7R) between BOOT and
PHASE pins.
24
PVCC Output of the 5V LDO and input for the LGATE and UGATE MOSFET driver circuits. Place a high quality low ESR ceramic
capacitor (4.7μF, X7R) in close proximity to the pin.
25
GND PAD Return of logic bias supply VCC. Connect directly to system ground plane with at least 5 vias.

NOTES:
1. Add “-T” suffix for 6k units, “-T7A” = suffix for 250 units and “-TK” for 1k units. 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 product information page for ISL68200. For more information on MSL please see techbrief TB363.
