TPS62090QRGTRQ1

Texas Instruments · DC-DC Converters · VQFN-16-EP(3x3)

TPS62090QRGTRQ1 from Texas Instruments, in a VQFN-16-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SW bidirectional Switch pin of the power stage; the datasheet lists it as I/O and it is bonded together with pin 2.
2 SW bidirectional Switch pin of the power stage; the datasheet lists it as I/O and it is bonded together with pin 1.
3 FREQ input Selects the switching frequency: Low gives a typical 2.8 MHz and High gives a typical 1.4 MHz; it has an active pulldown of typically 400 kΩ and can be left floating for 2.8 MHz operation.
4 PG output Power-good open-drain output that is high impedance when VOUT is in regulation and pulled low when the output is below nominal; the pullup must not connect to a voltage higher than the device input voltage.
5 FB input Feedback pin; for the adjustable version a resistor divider from the output sets the output voltage.
6 AGND power_in Analog ground; the exposed thermal pad is connected to AGND.
7 CP bidirectional Internal charge-pump flying capacitor terminal; connect a 10-nF capacitor between CP and CN.
8 CN bidirectional Internal charge-pump flying capacitor terminal; connect a 10-nF capacitor between CP and CN.
9 SS input Soft-start control pin; a capacitor on this pin sets the soft-start time, and leaving it floating sets the minimum start-up time.
10 AVIN power_in Bias supply input voltage pin for the device; the recommended VIN range is 2.5 V to 6 V.
11 PVIN power_in Power supply input voltage pin; the recommended VIN range is 2.5 V to 6 V and the absolute maximum rating is -0.3 V to 7 V.
12 PVIN power_in Power supply input voltage pin; the recommended VIN range is 2.5 V to 6 V and the absolute maximum rating is -0.3 V to 7 V.
13 EN input Device enable; must be pulled high to enable the device and pulled low to disable it, with an internal pulldown of typically 400 kΩ active when EN is low.
14 PGND power_in Power ground connection.
15 PGND power_in Power ground connection.
16 VOS input Output voltage sense pin that must be connected to the output voltage.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
