TPS54560BQDDAQ1

Texas Instruments · DC-DC Converters · SO-8

TPS54560BQDDAQ1 from Texas Instruments, in a SO-8. 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 A bootstrap capacitor is required between BOOT and SW; if its voltage falls below the minimum needed to operate the high-side MOSFET, the output is switched off until the capacitor is refreshed.
2 VIN power_in Input supply voltage with a 4.5 V to 60 V operating range.
3 EN input Enable terminal with an internal pull-up current source; pull below 1.2 V to disable and float to enable, with the input undervoltage lockout adjustable through two resistors.
4 RT/CLK input Resistor timing and external clock terminal: an external resistor to ground sets the switching frequency, and pulling the terminal above the PLL upper threshold makes it a synchronization input.
5 FB input Inverting input of the transconductance (gm) error amplifier.
6 COMP output Error amplifier output and input to the output switch current (PWM) comparator; frequency compensation components connect to this terminal.
7 GND power_in Ground; must be electrically connected to the exposed PowerPAD on the printed circuit board for proper operation.
8 SW output Source of the internal high-side power MOSFET and the switching node of the converter.
