TPS62A04ABDRLR

Texas Instruments · Global Sourcing Parts · SOT-563

TPS62A04ABDRLR from Texas Instruments, in a SOT-563. 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 GND power_in Ground pin for the device.
2 SW output Switch pin connected to the internal FET switches and the inductor terminal; absolute maximum is -0.3V to VIN+0.3V DC and -3.0V to 10V for transients under 10ns.
3 VIN power_in Power supply voltage pin, operating from 2.5V to 5.5V.
4 EN input Device enable logic input: logic high enables the device, logic low shuts it down, with rising threshold 1.2V and falling threshold 0.4V, and the pin must not be left floating.
5 FB input Feedback pin for the internal control loop, connected to an external feedback divider, with an absolute maximum of 3V.
6 PG output Power-good open-drain output; the pullup resistor cannot be connected to any voltage higher than 5.5V, and if unused it should be left open or connected to GND.
