CONTROLLER
COMMENTS
ISL6336B
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.

ISL6622,
12V
Dual Output
Yes
ISL6622A,ISL6622B
(Single Phase)
Yes
For phases that are active in PSI# mode and its coupled
channel in coupled inductor applications. Can also be
used on all channels.
ISL6620, ISL6620A
5V
Dual Output
Yes
(Single Phase)
No
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
ISL6596, ISL6609
5V
Dual Output
No
(Single Phase)
No
Can be used with phases that are inactive in PSI# mode
ISL6614, ISL6614A
12V
Quad Output
No
(Two Phase)
No
Can be used with phases that are inactive in PSI# mode
ISL6610, ISL6610A
5V
Quad Output
No
(Two Phase)
No
Can be used with phases that are inactive in PSI# mode
NOTE: Intersil 5V and 12V drivers are mostly pin-to-pin compatible and allow for dual footprint layout implementation to optimize MOSFET selection and
efficiency. Dual = One Synchronous Channel; Quad = Two Synchronous Channels.
