Functions
Power supply terminal
In standard condition 3.1 V to 5.5 V*
VIN
* : 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, FUJITSU MICRO-
ELECTRONICS recommends changing the output capacity (C1, C2) to 10 μF.
VOUT1, VOUT2
Output terminals
(VOUT1: CH1, VOUT2: CH2)
VCTL
Power supply terminal for setting the CTL1, CTL2 and CTLP terminals.
Use by connecting with VIN (When SW is mounted).
CTL1, CTL2
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
MODE1, MODE2
Direct supply terminal of MODE (CH1 : for MODE1, CH2 : for MODE2)
MODE1, MODE2 = 0 V to 0.4 V(Max)
: PFM/PWM mode
MODE1, MODE2 = OPEN(Remove R1 and R4) : PWM mode
VREF
Reference voltage output terminal
VREF = 1.30 V (Typ.)
VREFIN1, VREFIN2
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 chan-
nel.
VDET
Voltage input terminal for voltage detection
CTLP
Voltage detection circuit block control terminal
CTLP = L : Voltage detection circuit block stop
CTLP = H : Normal operation
XPOR
Voltage detection circuit output terminal
The N-ch MOS open drain circuit is connected.
VXPOR
Pull-up voltage terminal for the XPOR terminal
PGND
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.
AGND
Ground terminal
