MP1470BGJ-Z
Monolithic Power Systems · DC-DC Converters · TSOT-23-6
MP1470BGJ-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 | GND | power_in | System ground and reference ground of the regulated output voltage; it requires extra care during PCB layout and should be connected to GND with copper traces and vias. |
| 2 | SW | output | Switch output; connect using a wide PCB trace. |
| 3 | IN | power_in | Supply voltage for the MP1470B, which operates from a 4.7V to 16V input rail; it requires C1 to decouple the input rail and should be connected using a wide PCB trace. |
| 4 | FB | input | Feedback connected to the tap of an external resistor divider from the output to GND to set the output voltage; the frequency foldback comparator lowers the oscillator frequency when FB drops below 140mV to prevent current-limit runaway during a short-circuit fault. |
| 5 | EN | input | Enable pin: driving EN high enables the MP1470B, and for automatic start-up EN should be connected to VIN through a 100kΩ resistor. |
| 6 | BST | passive | Bootstrap pin: connect a capacitor and a resistor between SW and BST to form a floating supply across the high-side switch driver, using a 1µF BST capacitor. |
