TPS57040QDGQRQ1

Texas Instruments · DC-DC Converters · HVSSOP-10-EP-0.5mm

TPS57040QDGQRQ1 from Texas Instruments, in a HVSSOP-10-EP-0.5mm. 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 BOOT output Bootstrap capacitor supply pin; output device is forced off if voltage drops below the minimum required by the output device.
2 VIN power_in Input supply voltage pin accepting 3.5 V to 42 V.
3 EN input Enable pin with internal pull-up current source; pull below 1.2 V to disable or float to enable device and adjust input undervoltage lockout with two resistors.
4 SS/TR input Slow-start and tracking input pin; external capacitor sets output rise time and voltage on this pin overrides internal reference for tracking and sequencing.
5 RT/CLK input Resistor timing and external clock input pin; holds fixed voltage with external resistor to ground for switching frequency setting or becomes high impedance clock input if pulled above PLL upper threshold.
6 PWRGD output Open drain power-good output; asserts low when output voltage is low due to thermal shutdown, dropout, overvoltage, or EN shutdown.
7 VSENSE input Inverting input node of the transconductance error amplifier for output voltage feedback.
8 COMP output Error amplifier output node and input to the output switch current comparator; connect frequency compensation components to this pin.
9 GND power_in Ground return pin.
10 PH input Source of the internal high-side power MOSFET switching node connecting to external inductor.
11 Thermal Pad power_in Exposed thermal pad on printed circuit board electrically connected to GND; must be connected for proper thermal and electrical operation.
