Pin Functions

PIN I/O DESCRIPTION
NAME NO.
C1+ 6 — Positive terminal of the flying capacitor C1
C1− 8 — Negative terminal of the flying capacitor C1
C2+ 15 — Positive terminal of the flying capacitor C2
C2− 13 — Negative terminal of the flying capacitor C2
ENABLE 3 I ENABLE input. Connect ENABLE to IN for normal operation. When ENABLE is a logic low, the device turns off and the supply current decreases to 0.05 µA. The output is disconnected from the input when the device is placed in shutdown.
FB 4 I Feedback input. Connect FB to OUT as close to the load as possible to achieve best regulation. A resistive divider is on the chip to match the output voltage to the internal reference voltage of 1.21 V.
GND 1, 2, 19, 20 — Ground. Analog ground for internal reference and control circuitry. Connect to PGND through a short trace.
IN 7,14 I Supply input. Bypass IN to PGND with capacitor CIN. Connect both IN terminals through a short trace.
LBO/PG 17 O Low battery detector output (TPS60140) or power good output (TPS60141). Open-drain output of the low-battery indicator or power-good comparator. It can sink 1 mA. TI recommends a 100-kΩ to 1-MΩ pullup. Leave the terminal unconnected if the low-battery or power-good detector function is not used.
LBI/NC 18 I Low battery detector input (TPS60140 only). The voltage applied to this terminal is compared to the internal 1.21-V reference voltage. Connect the terminal to ground if the low-battery comparator is not used. On the TPS60141, this terminal is not connected to the chip and should remain unconnected.
NC 16 — Not connected
OUT 5 O Regulated 5-V power output. Bypass OUT to PGND with the output filter capacitor COUT.
PGND 9−12 — Power ground. The charge-pump current flows through this terminal. Connect all PGND terminals together.
