ISL6334A Intersil Corporation, ISL6334A Datasheet - Page 3

• Manufacturer Part Number: ISL6334A
• Description: 4-Phase PWM Controller
• Manufacturer: Intersil Corporation

Controller and Driver Recommendation
NOTE: 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.

DRIVER
When PSI# is asserted low, the remained channel transmits a special PWM protocol that can be recognized only by the dedicated
VR11.1 drivers ISL6622/ISL6620 for Diode Emulation (DCM) operation. The dropped channel remains in tri-state.
When PSI# is asserted low, the remained channel transmits normal CCM PWM that can be recognized by any Intersil driver such
as ISL6612/ISL6614, ISL6596, ISL6610, and even ISL6622/ISL6620. The dropped channel remains in tri-state.
