94% (typ) of its regulation voltage. The PGOOD asserts low during soft-start. Connect PGOOD to BIAS

or a positive voltage lower than 5.5V with a pull-up resistor to indicate buck output status.

SYNC

External Clock Synchronization Input. Connect SYNC low to enable skip-mode operation. Connect

SYNC high for forced PWM operation. Connect a valid external clock signal to SYNC to enable external

clock synchronization.

SYNCOUT

180° Out-of-Phase Clock Output. In dual-phase operation, connect SYNCOUT to BIAS to configure the

IC as a target, and connect SYNCOUT of the controller to SYNC of the target. Leave SYNC open in

single-phase operation.
