Functional Pin Description Pin Configuration WQFN-32L 4x4 (TOP VIEW) Pin No. 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.
