NAME
ONA
FUNCTION
On-Control Input. When ONA = high
or
ONB
= low, the device turns on (Table 1).
2, 3, 4
LX
Drain of N-Channel Power Switch. Connect pins 2, 3, and 4 together. Connect external
Schottky diode from LX to OUT.
5, 8
GND
Ground
6
SS/LIM
Soft-Start and/or Current-Limit Input. Connect a capacitor from SS/LIM to GND to control the
rate at which the device reaches current limit (soft-start). To reduce the current limit from the
preset values, connect a resistor from SS/LIM to GND (see
Design Procedure
). During
shutdown, this pin is internally pulled to GND to discharge the soft-start capacitor.
7
REF
1.26V Voltage Reference Output. Bypass with a 0.22
μ
F capacitor to GND. Maximum REF load
is 50
μ
A.
9
OUT
Output Voltage Sense Input. The device is powered from OUT. Bypass with a 0.1
μ
F to PGND
with less than 5mm trace length. Connect a 2
series resistor from the output filter capacitor to
OUT (Figure 1).
10
FB
DC-DC Converter Feedback Input. Connect FB to GND for internally set output voltage (see
3.3
/
5 pin description). Connect a resistor-divider from the output to set the output voltage in
the +2.5V to +5.5V range. FB regulates to +1.25V (Figure 4).
11, 12, 13
PGND
Power Ground, Source of N-Channel Power MOSFET Switch
14
3.3/5
Output Voltage Selection Pin. When FB is connected to GND, the regulator uses internal
feedback to set the output voltage. 3.3
/
5 = low sets output to 3.3V; 3.3
/
5 = high sets output to
5V. If an external divider is used at FB, connect 3.3
/
5 to ground.
15
CLK
Clock Input for the DC-DC Converter. Connect to OUT for internal oscillator. Optionally, drive
with an external clock for external synchronization.
16
ONB
Shutdown Input. When
ONB
= high
and
ONA = low, the device turns off (Table 1).
