Pin Name
Pin Function
25, 1
BOOT[1:2]
Bootstrap supply for high-side gate MOSFET driver.
2
VR_HOT#
Thermal monitor output. (Active low).
3
ALERT#
SVID alert. (Active low).
4
VDIO
VR and CPU data transmission interface.
5
VCLK
Synchronous clock from the CPU.
6
SET3
Function settings for loop response speed-up adaptive quick response (AQR)
trigger level, zero current detection, sum OCP ratio and undershoot
suppression.
7
SET2
Function settings for anti-overshoot trigger level, current gain (Ai), DVID fast
slew rate, acoustic noise suppression and high frequency ACLL voltage
compensation in PS1.
8
SET1
Function settings for ICCMAX, TON width setting (switching frequency) and
VBOOT. Connect the SET1 pin to 5V and turn on the VRON pin, if the soldering
is good, the output voltage is 1.8V.
9
PSYS
System input power monitor. Place the PSYS resistor as close to the IC as
possible.
10
VCC
Controller power supply. Connect this pin to 5V and place an RC filter, R = 6.2
and C = 4.7
F. The decoupling capacitor should be as close as physically
possible to the VCC pin.
11
IMON
Current monitor output for controller. This pin outputs a voltage proportional to
the output current.
