MP2456GJ-Z from Monolithic Power Systems, in a TSOT-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 | BST | passive | Bootstrap pin: connect a capacitor between the SW and BST pins to form a floating supply that drives the power switch gate above the supply voltage (BST capacitor is 0.1µF-1µF per the application notes). |
| 2 | GND | power_in | Ground and voltage reference for the regulated output voltage; it requires special layout so that it is isolated from the D1-to-C1 ground path to prevent switching current spikes from inducing noise. |
| 3 | FB | input | Feedback input that sets the output voltage through an external resistor divider from the output to GND; the frequency foldback comparator lowers the oscillator frequency when FB is below 250mV. |
| 4 | EN | input | On/off input: pull EN above 1.35V to turn the device on, and keep the EN sink current at or below 100µA (EN may be tied to VIN through a resistor for automatic enable). |
| 5 | IN | power_in | Supply voltage input for the unregulated 4.5V-to-50V input range; input capacitor C1 is required to prevent large voltage spikes at the input. |
| 6 | SW | output | Switch output connecting the internal power MOSFET to the inductor and external Schottky diode D1; the datasheet gives no further electrical limits for this pin. |
