TPS54260DGQ

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

TPS54260DGQ 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 passive Bootstrap capacitor is required between BOOT and PH; if the capacitor voltage falls below the minimum required by the output device, the output is forced off until the capacitor is refreshed.
2 VIN power_in Input supply voltage, 3.5 V to 60 V.
3 EN input Enable pin with internal pull-up current source; pull below 1.2 V to disable, float to enable, or adjust the input undervoltage lockout with two resistors.
4 SS/TR input Slow-start and tracking pin where an external capacitor sets the output rise time, and its voltage overrides the internal reference so it can be used for tracking and sequencing.
5 RT/CLK input Resistor timing and external clock pin; a resistor to ground sets the switching frequency, and pulling above the PLL upper threshold turns it into a high-impedance synchronization clock input.
6 PWRGD output Open-drain power-good output that asserts low if output voltage is low due to thermal shutdown, dropout, over-voltage or EN shutdown.
7 VSENSE input Inverting node of the transconductance (gm) error amplifier.
8 COMP output Error amplifier output and input to the output switch current comparator; frequency compensation components connect to this pin.
9 GND power_in Ground.
10 PH output Source of the internal high-side power MOSFET.
11 Thermal Pad power_in Exposed thermal pad that must be electrically connected to the GND pin on the printed circuit board for proper operation.
