DESCRIPTION
SS is used to adjust the soft-start time. Connect a capacitor from SS to SGND to adjust the soft-
start time (current sharing). CSS should not be larger than 33nF. This capacitor, along with an
internal 5µA current source sets the soft-start interval of the converter, tSS.
CSS[μF] = 6.25 ⋅ tSS[s]

Input supply voltage for the logic. VDD to be at the same potential as VIN +0.3/-0.5V.
Negative supply for the power stage of Channel 1.
Switching node connection for Channel 1. Connect to one terminal of inductor for VOUT1.
Input supply voltage. Connect 22µF ceramic capacitor to power ground per channel.
The exposed pad must be connected to the SGND pin for proper electrical performance. Add as much
vias as possible for optimal thermal performance.

NOTES:
1. 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 ISL8036, ISL8036A. For more information on MSL,
please see Technical Brief TB363.
