PGND

1

PWR

Power ground.

SW

2

PWR

The switch pin of the boost converter. It is connected to the drain of the internal Power MOSFETs.

VIN

3

I

IC power supply input.

CC

4

I

Constant output current programming pin. Connect a resistor to this pin to program the constant output

current. A capacitor should be connected in parallel to stabilize the control loop. Connect this pin to the

AGND pin to disable the constant output current function.

AGND

5

I/O

Analog ground.

FB

6

I

Voltage feedback pin of adjustable version (TPS61236P). Must be connected to VOUT pin on fixed

output voltage version (TPS61235).

EN

7

I

Enable logic input. Logic high enables the device. Logic low disables the device and puts it in

shutdown mode. This pin must be terminated and cannot be left floating. An external pull down resistor

connected to this pin is recommended.

INACT

8

O

Load status indication. Open drain output. Can be left float or connected to AGND pin if not used.

VOUT

9

PWR

Boost converter output.
