# MT2496

**Aerosemi** · DC-DC Converters · SOT-23-6

MT2496 from Aerosemi, 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 | BS | passive | Bootstrap pin: a capacitor must be connected between SW and BS to form a floating supply for the high-side switch driver, with BS limited to (VSW-0.3V) to (VSW+5V). |
| 2 | GND | power_in | Analog ground pin. |
| 3 | FB | input | Adjustable-version feedback input that must be connected to the center point of the external resistor divider, with a 0.6V regulated reference and absolute voltage limits of -0.3V to 6V. |
| 4 | EN | input | Enable input: drive logic-high to enable the IC and logic-low to disable it into micro-power shutdown, with absolute voltage limits of -0.3V to 17V. |
| 5 | VIN | power_in | Power supply pin with an input supply voltage range of 4.5V to 16V and an absolute maximum of 17V. |
| 6 | SW | output | Switching pin (internal power MOSFET output to the inductor), with absolute voltage limits of -0.3V to (VIN+0.5V). |
