TPS57114MRTETEP

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

TPS57114MRTETEP from Texas Instruments, in a WQFN-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 VIN power_in Input supply voltage, 2.95 to 6 V.
2 VIN power_in Input supply voltage, 2.95 to 6 V.
3 GND power_in Power ground; electrically connect directly to the thermal pad under the IC.
4 GND power_in Power ground; electrically connect directly to the thermal pad under the IC.
5 AGND power_in Analog ground; connect electrically to GND close to the device.
6 VSENSE input Inverting node of the transconductance (gm) error amplifier.
7 COMP output Error amplifier output and input to the output-switch current comparator; connect frequency-compensation components to this pin.
8 RT/CLK input Resistor-timing or external-clock input pin.
9 SS/TR input Slow start and tracking; an external capacitor sets the output-voltage rise time, and the pin can also be used for tracking.
10 PH power_out Source of the internal high-side power MOSFET and drain of the internal low-side (synchronous) rectifier MOSFET.
11 PH power_out Source of the internal high-side power MOSFET and drain of the internal low-side (synchronous) rectifier MOSFET.
12 PH power_out Source of the internal high-side power MOSFET and drain of the internal low-side (synchronous) rectifier MOSFET.
13 BOOT passive Requires a bootstrap capacitor between BOOT and PH; if its voltage is below the BOOT UVLO minimum the output is forced off until the capacitor recharges.
14 PWRGD output Open-drain output that asserts low if output voltage is low due to thermal shutdown, overcurrent, overvoltage, undervoltage, or EN shutdown.
15 EN input Enable pin with internal pullup current source; pull below 1.2 V to disable, float to enable, or use two resistors to set the on-off threshold (adjust UVLO).
16 VIN power_in Input supply voltage, 2.95 to 6 V.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
