DESCRIPTION
Digital ground. Connect to low impedance ground plane.
Clock synchronization input. Used to set the frequency of the internal switch clock, to sync to an external
clock or to output internal clock.
Serial address select pins. Used to assign unique address for each individual device or to enable certain
management features.
Current limit select. Sets the overcurrent threshold voltage for ISENA, ISENB.
Serial clock. Connect to external host and/or to other ZL devices.
Serial data. Connect to external host and/or to other ZL devices.
Serial alert. Connect to external host if desired.
Loop compensation selection pin.
Output voltage selection pins. Used to set V OUT set-point and V OUT max.
External voltage monitoring (Can be used for external driver bias monitoring for Power-good).
No Connect.
Tracking sense input. Used to track an external voltage source.
Differential Output voltage sense feedback. Connect to positive output regulation point.
Differential Output voltage sense feedback. Connect to negative output regulation point.
Differential voltage input for current sensing.
Differential voltage input for current sensing. High voltage (DCR).
PWM Gate low signal.
Connect to low impedance ground plane. Internal connection to SGND.
PWM Gate High signal.
Internal 5V reference used to power internal drivers.

Single wire DDC bus (Current sharing, interdevice communication).
V OUT margin control.
Configuration pin. Used to control the switching phase offset, sequencing and other management features.
Enable. Active signal enables PWM switching.
Soft-start delay and ramp select. Sets the delay from when EN is asserted until the output voltage starts to
ramp and the ramp time.

NOTES:
5. I = Input, O = Output, PWR = Power or Ground. M = Multi-mode pins.
6. The SYNC pin can be used as a logic pin, a clock input or a clock output.
7. V DD is measured internally and the value is used to modify the PWM loop gain.
