• Setup and checkup
(1) Setup
1. Connect the CTL1 terminal and the CTL2 terminal to the VIN terminal.
2. Put it into “L” state by connecting the CTLP terminal to the AGND pad.
3. Connect the power supply terminal to the VIN terminal, and the power supply GND terminal to the PGND
terminal. Make sure PGND is connected to the PGND terminal next to the VIN terminal.
(Example of setting power-supply voltage : 3.7 V)
(2) Checkup
Supply power to VIN. The IC is operating normally if VOUT1 = 2.5 V (Typ) and VOUT2 = 1.8 V (Typ).
