TMI · DC-DC Converters · SOT-23-6
TMI32530 from TMI, in a SOT-23-6. 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 TMI32530 (no electrical limits are stated for this pin in the datasheet). |
| 2 | LX | power_out | Switching pin; LX voltage is rated -0.3 V to 20 V, with -5 V to 22 V allowed for transients shorter than 10 ns. |
| 3 | IN | power_in | Power supply pin; the recommended input voltage range is 4.5 V to 18 V. |
| 4 | FB | input | Output voltage feedback input, connected to the center point of the external resistor divider; the regulated feedback voltage is 0.6 V (0.591 V to 0.609 V at 25 °C) and FB is rated -0.3 V to 6 V. |
| 5 | EN | input | Drive to logic-high to enable the IC and to logic-low to disable it into micro-power shutdown; do not let this pin float; the rising threshold is 0.8 V to 1.05 V with 100 mV hysteresis. |
| 6 | BS | power_out | Bootstrap pin; a capacitor connected between LX and BS is required to form a floating supply across the high-side switch driver; BS is rated -0.3 V to 23 V. |
