Texas Instruments · Charge Pumps · VQFN-16-EP(3x3)

TPS62090RGTR from Texas Instruments, in a VQFN-16-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SW output Switch pin of the power stage. Connect to the external inductor. Absolute maximum voltage range -0.3 V to VIN + 0.3 V. Pins 1 and 2 are tied together internally to the switching node.
2 SW output Switch pin of the power stage. Connect to the external inductor. Absolute maximum voltage range -0.3 V to VIN + 0.3 V. Pins 1 and 2 are tied together internally to the switching node.
3 FREQ input Switching frequency select. FREQ = Low sets typical switching frequency to 2.8 MHz; FREQ = High sets it to 1.4 MHz. Has an internal ~400 kOhm pull-down resistor and can be left floating for 2.8 MHz operation.
4 PG output Power good open-drain output. High impedance when output voltage is within regulation, pulled low when output is below nominal. Pull-up resistor must not be tied to a voltage higher than VIN. Sink current up to 1 mA.
5 FB input Feedback pin. For adjustable version, connect a resistor divider from output to set VOUT (VFB = 0.8 V typ). For fixed-output versions may be tied to GND for improved thermal performance; has ~400 kOhm pull-down active when EN is low.
6 AGND power_in Analog ground reference for the control circuitry. Must be connected to the exposed thermal pad and to PGND on the PCB.
7 CP passive Internal charge-pump flying capacitor terminal. Connect a 10 nF capacitor between CP and CN. Absolute max -0.3 V to VIN + 7.0 V.
8 CN passive Internal charge-pump flying capacitor terminal. Connect a 10 nF capacitor between CP and CN. Absolute max -0.3 V to VIN + 7.0 V.
9 SS input Softstart control pin. A capacitor to GND sets the softstart time using the ~7.5 uA softstart current. Leaving it floating uses the minimum start-up time. Also used for output voltage tracking.
10 AVIN power_in Bias supply input voltage pin for the internal analog circuitry. Recommended input range 2.5 V to 6 V; absolute max 7 V. Typically tied to PVIN with local decoupling.
11 PVIN power_in Power supply input voltage pin for the power stage. Recommended input range 2.5 V to 6 V; absolute max 7 V. Pins 11 and 12 must be tied together and bypassed with a low-ESR ceramic capacitor (typ. 10 uF).
12 PVIN power_in Power supply input voltage pin for the power stage. Recommended input range 2.5 V to 6 V; absolute max 7 V. Pins 11 and 12 must be tied together and bypassed with a low-ESR ceramic capacitor (typ. 10 uF).
13 EN input Device enable. Pull high to enable; pull low to disable. Has an internal ~400 kOhm pull-down resistor active when EN is low. VIH >= 1 V, VIL <= 0.4 V.
14 PGND power_in Power ground return for the power stage. Pins 14 and 15 must be tied together and connected to the exposed thermal pad and system ground plane.
15 PGND power_in Power ground return for the power stage. Pins 14 and 15 must be tied together and connected to the exposed thermal pad and system ground plane.
16 VOS input Output voltage sense pin. Must be connected directly to the regulated output voltage node (VOUT) at the load side of the output capacitor.
17 EP power_in Exposed thermal pad, internally connected to AGND. Must be soldered to the PCB ground plane for electrical connection and thermal reliability.
