DESCRIPTION
NAME
NO.
AGND
1
Analog ground. Return for compensation network/output divider, slow-start capacitor, VBIAS capacitor, and RT
resistor. Connect PowerPAD connection to AGND.
BOOT
5
Bootstrap output. 0.022-F to 0.1-F low-ESR capacitor connected from BOOT to PH generates floating drive for the
high-side FET driver.
COMP
3
Error amplifier output. Connect frequency compensation network from COMP to VSENSE
ENA
19
Enable input. Logic high enables oscillator, PWM control and MOSFET driver circuits. Logic low disables operation
and places device in a low quiescent current state.
PGND
11-13
Power ground. High current return for the low-side driver and power MOSFET. Connect PGND with large copper
areas to the input and output supply returns, and negative terminals of the input and output capacitors. A single-point
connection to AGND is recommended.
PH
6-10
Phase input/output. Junction of the internal high-side and low-side power MOSFETs, and output inductor.
RT
20
Frequency setting resistor input. Connect a resistor from RT to AGND to set the switching frequency, fs.
REFIN
18
External reference input. High impedance input to slow-start and error amplifier circuits.
STATUS
4
Open-drain output. Asserted low when VIN < UVLO, VBIAS and internal reference are not settled or the internal
shutdown signal is active. Otherwise STATUS is high.
VBIAS
17
Internal bias regulator output. Supplies regulated voltage to internal circuitry. Bypass VBIAS pin to AGND pin with a
high quality, low-ESR 0.1-F to 1.0-F ceramic capacitor.
VIN
14-16
Input supply for the power MOSFET switches and internal bias regulator. Bypass VIN pins to PGND pins close to
device package with a high-quality, low-ESR 10-F ceramic capacitor.
VSENSE
2
Error amplifier inverting input. Connect to output voltage compensation network/output divider.
