16

CSREF

Current Sense Reference. Non-Inverting input of the current sense amp. Sense

point for the output voltage used for OVP and PWRGD.

17

CSSUM

Current Sense Summing node. Inverting input of the current sense amp.

18

CSCOMP

Current Sense Compensation node. Output of the current sense amplifier. This

pin is used, in conjunction with CSSUM to set the output droop compensation and

current loop response.

19

GND

Ground. Signal ground for the device.

20–23

SW[4:1]

Phase Current Sense/Balance inputs. Phase-to-phase current sense and

balancing inputs. Unused phases should be left open.

24–27

PWM[4:1]

PWM outputs. CMOS outputs for driving external gate driver such as the FAN5009.

Unused phases should be connected to Ground.

28

VCC

Chip Power. Bias supply for the chip. Connect directly to a +12V supply. Bypass

with a 1µF MLCC capacitor.
