PIN NAME FUNCTION
1 FOSC
Resistor-Programmable Switching-Frequency-Setting Control Input. Connect a resistor from FOSC to
AGND to set the switching frequency.
2 OUT
Switching-Regulator Output. OUT also provides power to the internal circuitry when the output voltage of
the converter is set between 3V to 5V during standby mode.
3 FB
Feedback Input. Connect an external resistive divider from OUT to FB and AGND to set the output
voltage. Connect to BIAS to set the output voltage to 5V or 3.3V.
4 COMP
Error-Amplier Output. Connect an RC network from COMP to AGND for stable operation. See the
Compensation Network section for more details.
5 BIAS
Linear Regulator Output. BIAS powers up the internal circuitry. Bypass with a minimum of 2.2µF ceramic
capacitor to ground.
6 AGND Analog Ground
7 EN
SUP Voltage-Compatible Enable Input. Drive EN low to disable the devices. Drive EN high to enable the
devices.
8, 9 SUPSW
Internal High-Side Switch Supply Input. SUPSW provides power to the internal switch. Bypass SUPSW
to PGND with a 0.1µF and 4.7µF ceramic capacitors.
10 SUP
Voltage-Supply Input. SUP powers up the internal linear regulator. Bypass SUP to PGND with a 2.2µF
ceramic capacitor.
11 PGOOD
Open-Drain, PGOOD Output. PGOOD asserts when V
OUT
is above 95% regulation point. PGOOD goes
low when V
OUT
is below 92% regulation point.
