CONTROLLER
COMMENTS
ISL6336
When PSI# is asserted (LOW), the controller generates a 3-level PWM pattern on the phases that are active in PSI# mode. The
active phases in PSI# mode must use VR11.1 drivers, ISL6622, ISL6620 for diode emulation.
ISL6336A
When PSI# is asserted (LOW), the PWM pattern has only high and low states except for fault modes. The controller can be used
with any Intersil driver such as ISL6612, ISL6614, ISL6609, ISL6610. ISL6622, ISL6620 can also be used.

No
Use for phases that are active in PSI# mode and its
coupled channel in coupled inductor applications. Can
also be used on all channels.
ISL6612, ISL6612A
12V
Dual Output
No
(Single Phase)
No
Can be used with phases that are inactive in PSI# mode
or with all channels when using the ISL6336A

(Single Phase)
No
Can be used with phases that are inactive in PSI# mode
or with all channels when using the ISL6336A
ISL6614, ISL6614A
12V
Quad Output
No
(Two Phase)
No
Can be used with phases that are inactive in PSI# mode
or with all channels when using the ISL6336A
ISL6610
5V
Quad Output

(Two Phase)
No
Can be used with phases that are inactive in PSI# mode
or with all channels when using the ISL6336A
NOTE: Intersil 5V and 12V drivers are mostly pin-to-pin compatible and allow dual footprint layout to optimize MOSFET selection and efficiency. Dual = One
Synchronous Channel; Quad = Two Synchronous channels.
