TPS63020DSJR Pinout

Package: 14-VFDFN Exposed Pad

Notes

• Pin numbers 8, 9 are both L1 (inductor connection points)
• Pin numbers 6, 7 are both L2 (inductor connection points)
• Pin numbers 10, 11 are both VIN (supply voltage for power stage)
• Pin numbers 4, 5 are both VOUT (buck-boost converter output)
• The exposed thermal pad (EP) is connected to PGND (power ground)
• EN and PS/SYNC must not be left open
• PG (power good) is open-drain and can be left open if not used

over recommended free-air temperature range and over recommended input voltage range (typical at an ambient temperature range of 25°C) (unless otherwise noted)

over operating free-air temperature range (unless otherwise noted) (1)

The TPS6302x are high efficiency, low quiescent current, non-inverting buck-boost converters suitable for applications that need a regulated output voltage from an input supply that can be higher, lower, or equal to the output voltage. Output currents can go as high as 2 A in boost mode and as high as 4 A in buck mode. The average current in the switches is limited to a typical value of 4 A.
