DESCRIPTION

NAME

NO.

I/O

DESCRIPTION

COMP

2

Compensation of error amplifier. Connect R-C-C network to set frequency response of control loop. See the

Application section for more details.

EN

1

I

Chip-enable input. The converter is switched on if EN is set high and is switched off when EN is connected to ground

(shutdown mode).

FB

3

I

Feedback input for adjustable output voltage (TPS61000 only). The output voltage is programmed depending on the

values of resistors R1 and R2. For the fixed output voltage versions (TPS61001, 2, 3, 4, 5, 6), leave the FB pin

unconnected.

GND

4

Ground

LBI

9

I

Low-battery detector input. A low-battery signal is generated at the LBO pin when the voltage on LBI drops below the

threshold of 500 mV. Connect LBI to GND or VBAT if the low-battery detector function is not used. Do not leave this

pin floating.

LBO

10

O

Open-drain low-battery detector output. This pin is pulled low if the voltage on LBI drops below the threshold of

500 mV. A pull-up resistor should be connected between LBO and VOUT.

NC

8

Not connected

SW

7

I

Switch input pin. The node between inductor and anode of the rectifier diode is connected to this pin.

VBAT

6

I

Supply pin

VOUT

5

O

Output voltage. For the fixed output voltage versions, the integrated resistive divider is connected to this pin.
