TPS62093RGTR

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

TPS62093RGTR 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.
2 SW bidirectional Switch pin of the power stage.
3 FREQ input Selects the switching frequency: Low sets 2.8 MHz typical and High sets 1.4 MHz typical; the pin has an active pull-down of about 400 kΩ and can be left floating for 2.8 MHz operation.
4 PG output Open-drain power good output that is high impedance when the output is within regulation and pulled low when the output is below its nominal value; the pull-up resistor must not connect to a voltage higher than the device input voltage.
5 FB input Feedback pin; for the adjustable version a resistor divider is connected here to set the output voltage, while for the fixed-output versions it may be connected to GND and has a pull-down of about 400 kΩ that is active when EN is low.
6 AGND power_in Analog ground; the exposed thermal pad is connected to AGND.
7 CP bidirectional Internal charge pump flying capacitor pin; connect a 10 nF capacitor between CP and CN.
8 CN bidirectional Internal charge pump flying capacitor pin; connect a 10 nF capacitor between CP and CN.
9 SS input Softstart control pin; a capacitor on this pin sets the softstart time, and leaving it floating sets the minimum start-up time.
10 AVIN power_in Bias supply input voltage pin.
11 PVIN power_in Power supply input voltage pin.
12 PVIN power_in Power supply input voltage pin.
13 EN input Device enable; it must be pulled high to enable the device and pulled low to disable it, with a pull-down of about 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; it must be connected to the output voltage.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
