TPS62400DRCR

Texas Instruments · DC-DC Converters · VSON-10-EP(3x3)

TPS62400DRCR from Texas Instruments, in a VSON-10-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 ADJ2 input Feedback/adjust input for converter 2. On the adjustable TPS62400 connect an external resistor divider between VOUT2 and GND to set 0.6-VIN output. On fixed-output versions (TPS62401/2/3/4) this pin MUST be tied directly to the output; when the EasyScale interface is used it MUST also be tied directly to the output.
2 MODE/DATA bidirectional Dual-function pin. As MODE: low = Power-Save (PFM at light loads, auto PWM at heavy), high = forced PWM over full load range. As DATA: one-wire EasyScale serial interface to change output voltage of both converters, with open-drain acknowledge (drain current must not exceed 500 uA). Active when either EN1 or EN2 is high.
3 VIN power_in Supply voltage input, connect to VBAT. Recommended operating range 2.5 V to 6 V (absolute max 7 V). Bypass locally with a 10 uF ceramic capacitor.
4 FB1 input Direct feedback voltage sense input of converter 1. Connect directly to VOUT1; an internal feedforward capacitor is connected between this pin and the error amplifier. On fixed-output versions or when EasyScale is used, this pin is connected to an internal resistor divider.
5 DEF_1 input Defines the output voltage of converter 1. Acts as an analog input for output-voltage setting via an external resistor divider (TPS62400 adjustable) or as a digital input to select between two fixed default output voltages on the fixed variants (TPS62401/2/3/4). See the Device Options table for the default voltages.
6 SW1 power_out Switch node of converter 1 (400 mA). Connect the external inductor (typ. 2.2 uH) between this pin and VOUT1. Absolute max voltage 7 V.
7 EN1 input Enable input for converter 1, active high. VIH = 1.2 V min, VIL = 0.4 V max. Input leakage ~0.05 uA.
8 GND power_in Ground return for both converters. Must be connected together with the exposed PowerPAD on the die-attach side for proper thermal/electrical performance.
9 EN2 input Enable input for converter 2, active high. VIH = 1.2 V min, VIL = 0.4 V max. Input leakage ~0.05 uA.
10 SW2 power_out Switch node of converter 2 (600 mA). Connect the external inductor (typ. 2.2 uH) between this pin and VOUT2. Absolute max voltage 7 V.
11 PowerPAD power_in Exposed thermal pad on the underside of the VSON package. Must be soldered to the PCB ground plane and connected to GND (pin 8) for proper electrical and thermal performance.

Two STEP files. Same geometry, different body top:

File Size Use it when
tps62400drcr.step 283 KB You want the bare part, or you mark your own boards.
tps62400drcr-etched.step 2.5 MB You want the part with TPS62400DRCR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 600 faces against 74 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
