DESCRIPTION
SS is used to adjust the soft-start time. When SS pin is tied to VIN, SS time is 1.5ms. SS pin is tied to VIN only in dual
mode operation. SS pin is tied to CSS only in parallel mode operation, using only external compensation. Connect a
capacitor from SS to SGND to adjust the soft-start time (current sharing). C SS should not be larger than 33nF. This
capacitor, along with an internal 5μA current source sets the soft-start interval of the converter, t SS .
(EQ. 1)
C SS [ μ F ] = 6.25 ? t SS [ 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 .
