NAME
FUNCTION
Open-Drain Clock Output. SYNCOUT outputs 180N out-of-phase signal relative to the internal oscillator.
1
SYNCOUT Connect to OUT with a resistor between 100I and 1kW for 2MHz operation. For low frequency
operation, use a resistor between 1kW and 10kW.
Synchronization Input. The device synchronizes to an external signal applied to FSYNC. Connect
2
FSYNC FSYNC to AGND to enable skip mode operation. Connect to BIAS or to an external clock to enable
fixed-frequency forced PWM mode operation.
3
FOSC
Resistor-Programmable Switching Frequency Setting Control Input. Connect a resistor from FOSC to
AGND to set the switching frequency.
4
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.
5
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.
6
COMP
Error Amplifier Output. Connect an RC network from COMP to AGND for stable operation. See the
Compensation Network section for more information.
7
BIAS
Linear Regulator Output. BIAS powers up the internal circuitry. Bypass with a 1FF capacitor to ground.
8
AGND Analog Ground
9
BST
High-Side Driver Supply. Connect a 0.22FF capacitor between LX and BST for
proper operation.
10
EN
SUP Voltage Compatible Enable Input. Drive EN low to disable the device. Drive EN high to enable the
device.
11
SUP
Voltage Supply Input. SUP powers up the internal linear regulator. Bypass SUP to PGND with a 4.7FF
ceramic capacitor.
