FUNCTION
Power Ground. Source connection of the internal step-up regulator power switch.
Switching Node. Connect inductor/catch diode here and minimize trace area for lowest EMI.
Chip-Enable Control and OCP Set Input. When ENA = low, the step-up converter and op amp are
disabled, the LDO remains active, and the level-shifter outputs are high impedance.
Step-Up Regulator and Low-Dropout Regulator Supply. Bypass IN to AGND with a 1 F F or greater
ceramic capacitor.
Internal Linear Regulator Output. Bypass LDOO to AGND with a 1 F F capacitor.
Linear Regulator Feedback Input. Reference voltage is 1.24V nominal.
Gate-Shading Discharge Time Adjust
Step-Up Regulator Soft-Start Control
Exposed Backside Pad. Connect to the analog ground plane for proper electrical and thermal
performance.
