PINI/ODESCRIPTION
NO.NAME
1VINIIC power supply input
2ENIEnable logic input. Logic high voltage enables the device. Logic low voltage disables the device and turns it into shutdown mode.
3

MODE

I

Operation mode selection in the light load condition. When it is connected to logic high voltage, the device works in forced PWM mode. When it is connected to logic low voltage, the device works in auto PFM mode.

4

PG

O

Power good indicator and open drain output

5

FB

I

TPS61033: Voltage feedback of adjustable output voltage, when FB connect to VIN, output voltage is fixed 5.0V

TPS610333: Should be connected with VIN for fixed 5.0 V output voltage.

6

GNDPWRGround pin of the IC

7

SWPWRThe switch pin of the converter. It is connected to the drain of the internal low-side power MOSFET and the source of the internal high-side power MOSFET.
