TPS53219ARGTR

Texas Instruments · DC-DC Converters · QFN-16(3x3)

TPS53219ARGTR from Texas Instruments, in a QFN-16(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 TRIP input OCL threshold setting pin sourcing 10 µA typical at 25°C with 4700 ppm/°C temperature compensation and 0.2 V to 3 V programmable range.
2 EN input Enable pin with enable threshold 1.7-1.8 V and disable threshold 0.5 V, requiring 1-kΩ series resistor if source voltage exceeds 5.5 V.
3 VFB input Output feedback input connected to output voltage through resistor divider and compared against 0.6 V internal reference with ±0.8% tolerance.
4 RF input Switching frequency selection pin connected to GND or VREG through resistor for selection of eight preset frequencies from 250 kHz to 970 kHz.
5 MODE input Soft-start time and operational mode selection pin with four selectable soft-start times from 0.7 ms to 5.6 ms.
6 VDD power_in Power supply input with operating range 4.5 V to 25 V and typical quiescent current of 420-590 µA at no load condition.
7 GND power_in Analog ground reference pin for internal circuitry, must be connected to GND plane at single point.
8 PGND power_in Power ground pin for gate drivers and MOSFET source connections, connected to GND plane.
9 VREG power_out 6.2 V LDO regulator output providing 5.76-6.67 V over 0-50 mA output current range for internal and gate driver supply.
10 VDRV power_in Gate drive supply voltage input accepting 4.5 V to 6.5 V from external source or connected to VREG.
11 DRVL output Low-side MOSFET gate driver output with 0.5-1.2 Ω on-resistance and 10-35 ns dead-time delay to DRVH.
12 SW power_out Synchronous buck converter output node connecting the drain of low-side MOSFET to high-side MOSFET drain and output inductor.
13 DRVH output High-side floating MOSFET gate driver output with 0.7-1.8 Ω on-resistance, bootstrap powered between VBST and SW nodes.
14 VBST power_out Bootstrap supply pin for high-side gate driver with external capacitor connection from VBST to SW node, internally supplied from VREG.
15 NC unconnected No connection pin.
16 PGOOD tri_state Open-drain power-good output flag with 1-ms startup delay rising when output within specified voltage band and 2-µs delay falling outside band.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
