Functions
Power supply terminal
In standard condition 3.1 V to 5.5 V*
* : When the VIN/VOUT difference is to be held within 0.6 V or less, such as for devices with a
standard output voltage (VOUT1  2.5 V) when VIN < 3.1 V, Cypress recommends changing
the output capacity (C1, C2) to 10 F.
Output terminals
(VOUT1: CH1, VOUT2: CH2)
Power supply terminal for setting the CTL1, CTL2 and CTLP terminals.
Use by connecting with CTL1,CTL2 and CTLP.
Direct supply terminal of CTL (CTL1 : for CH1, CTL2 : for CH2)
CTL1, CTL2  0 V to 0.8 V (Typ.) : Shutdown
CTL1, CTL2  0.95 V (Typ.) to VIN (5 V Max) : Normal operation
TEST terminal
MODE1, MODE2  OPEN or GND
Reference voltage output terminal
VREF  1.30 V (Typ.)
External reference voltage input terminals
(VREFIN1 : for CH1, VREFIN2 : for CH2)
When an external reference voltage is supplied, connect it to the terminal for each channel.
Voltage input terminal for voltage detection
Voltage detection circuit block control terminal
CTLP  L : Voltage detection circuit block stop
CTLP  H : Normal operation
Voltage detection circuit output terminal
The N-ch MOS open drain circuit is connected.
Pull-up voltage terminal for the XPOR terminal
Ground terminal
Connect power supply GND to the PGND terminal next to the VIN terminal.
Connect output (load) GND to the PGND terminal between the VOUT1 terminal and the VOUT2 terminal.
