TMI3282

TMI · DC-DC Converters · SOT-23-6

TMI3282 from TMI, in a SOT-23-6. 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 GND power_in Ground pin. Return for the low-side power MOSFET and all internal control circuitry. Connect to a large copper pour for thermal dissipation.
2 LX power_out Switching node. Common drain of the internal high-side and low-side power MOSFETs. Connect to the external inductor. Absolute rating -0.3V to 20V.
3 IN power_in Power supply pin. Input voltage 3.5V to 18V (abs max 20V). Bypass with a low-ESR ceramic capacitor (typ. 22µF) placed close to the pin.
4 FB input Output voltage feedback input. Connect to the center tap of an external resistor divider from VOUT to GND. Internal reference is 0.8V (0.784V-0.816V). Absolute rating -0.3V to 6V.
5 EN input Enable input. Drive logic-high to enable the IC; drive logic-low to enter micro-power shutdown (~2µA). Do not leave floating. Absolute rating -0.3V to 20V.
6 BS passive Bootstrap pin. Connect a bootstrap capacitor between LX and BS to form a floating supply for the high-side MOSFET driver. Absolute rating -0.6V to 25V.
