TPS62740DSST

Texas Instruments · DC-DC Converters · WSON-12-EP(2x3)

TPS62740DSST from Texas Instruments, in a WSON-12-EP(2x3). 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 VIN power_in Power supply input pin for 2.2V to 5.5V; connect close to VIN terminal of 4.7µF minimum input capacitor.
2 SW output Internal MOSFET switch node; connect external inductor to this terminal for buck converter switching operation.
3 GND power_in Ground supply pin; connect close to GND terminal of input and output capacitors.
4 CTRL input Control input pin for LOAD output; high enables LOAD output (connects to VOUT), low disables and pulls LOAD to GND; must be terminated.
5 VOUT input Feedback voltage input pin for internal feedback divider network and regulation loop; connect directly to output capacitor with short trace; internal load switch connects LOAD to VOUT.
6 LOAD output Switched output controlled by CTRL pin; high at VOUT when CTRL high (system power supply), pulled to GND when CTRL low; provides soft switching and load control.
7 PG tri_state Power good open-drain output; high-impedance state indicates power good condition; connect external pull-up resistor for logic high level.
8 VSEL4 input Output voltage selection pin (MSB of 4-bit code); combined with VSEL3-VSEL1 selects output from 1.8V to 3.3V in 100mV steps per Table 1; must be terminated; changeable during operation.
9 VSEL3 input Output voltage selection input pin; combined with VSEL4, VSEL2, VSEL1 selects regulated output from 1.8V to 3.3V in 100mV steps per Table 1; must be terminated; changeable during operation.
10 VSEL2 input Output voltage selection input pin; combined with VSEL4, VSEL3, VSEL1 selects regulated output from 1.8V to 3.3V in 100mV steps per Table 1; must be terminated; changeable during operation.
11 VSEL1 input Output voltage selection pin (LSB of 4-bit code); combined with VSEL4-VSEL2 selects output from 1.8V to 3.3V in 100mV steps per Table 1; must be terminated; changeable during operation.
12 EN input Enable control input; high enables converter operation, low forces device into shutdown mode for low quiescent current; must be terminated.
13 EXPOSED THERMAL PAD passive Exposed pad (from the footprint; not named in the datasheet pin table).
