TMI3494

TMI · DC-DC Converters · ESOP-8

TMI3494 from TMI, in a ESOP-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 BS power_out High-side gate driver bootstrap pin that supplies the high-side LDMOS gate driver; connect a 0.1µF capacitor between BS and SW.
2 IN power_in Power input pin; the recommended operating input voltage range is 5 V to 40 V.
3 SW output Switch pin that connects to the external inductor; the absolute maximum input supply voltage on SW is -0.3 V to 45 V.
4 GND power_in Ground pin.
5 FB input Feedback pin that regulates to the internal 0.92 V reference (VFBTH 902 mV to 938 mV), with output voltage set by an external resistor divider.
6 COMP passive External compensation pin for the control loop.
7 ISET passive Current limit set pin; the output current limit is set by a resistor from ISET to GND, with a recommended RISET not smaller than 200 kΩ.
8 EN input Active-low enable pin: drive below 0.4 V to enable the regulator and above 1.4 V to turn it off; do not leave it floating.
9 GND power_in Ground exposed pad that should be connected to the power ground copper area with copper and vias.
