NAME
FUNCTION
1
SRC
Switch Input. Source of the internal high-voltage p-channel MOSFET. Bypass SRC to PGND with a
minimum 0.1μF capacitor close to the pins.
2
REF
Reference Bypass Terminal. Bypass REF to AGND with a minimum of 0.22μF close to the pins.
3
AGND
Analog Ground for Step-Up Regulator and Linear Regulators. Connect to power ground (PGND)
underneath the IC.
4
PGND
Power Ground. PGND is the source of the main step-up n-channel power MOSFET. Connect PGND to
the output-capacitor ground terminals through a short, wide PC board trace. Connect to analog ground
(AGND) underneath the IC.
