TPS54541DPRT

Texas Instruments · DC-DC Converters · WSON-10-EP(4x4)

TPS54541DPRT from Texas Instruments, in a WSON-10-EP(4x4). 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 gate drive is switched off until the capacitor is refreshed.
2 VIN power_in Input supply voltage with a 4.5 V to 42 V operating range.
3 EN input Enable pin with an internal pullup current source; pull below 1.2 V to disable and float to enable, and the input undervoltage lockout can be adjusted with two resistors.
4 SS/TR input Soft-start and tracking pin; an external capacitor sets the output rise time, and because this pin overrides the internal reference it can be used for tracking and sequencing.
5 RT/CLK input Resistor timing and external clock pin: an external resistor to ground sets the switching frequency, and pulling the pin above the PLL upper threshold makes it a high-impedance synchronization clock input.
6 FB input Inverting input of the transconductance (gm) error amplifier.
7 COMP output Error amplifier output and input to the output switch current (PWM) comparator; frequency compensation components connect to this pin.
8 GND power_in Ground pin, which must be electrically connected to the exposed thermal pad on the printed circuit board for proper operation.
9 SW output Source of the internal high-side power MOSFET and the switching node of the converter.
10 PWRGD output Power Good open-drain output that asserts low if the output voltage is out of regulation due to thermal shutdown, dropout, over-voltage, or EN shutdown.
11 Thermal Pad power_in Exposed thermal pad that must be electrically connected to the GND pin and the printed circuit board for proper operation.
