CONTROLLER
DRIVER
When PSI# is asserted low, the operating channels send a special PWM protocol that can be recognized only by the dedicated
VR11.1 drivers ISL6622/ISL6620 for Diode Emulation (DCM) operation. The disabled channels remain in tri-state.
When PSI# is asserted low, the operating channels send normal CCM PWM that can be recognized by any Intersil driver,
such as ISL6612/ISL6614, ISL6596, ISL6609, ISL6610, and even ISL6622/ISL6620. The disabled channels remain in
tri-state.
