MP1495SGJ-Z from Monolithic Power Systems, in a TSOT-23-8. 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 | AAM | input | Advanced Asynchronous Modulation pin: connect the tap of a resistor divider from VCC to set the AAM-to-CCM transition point, and drive it high (VCC) to force the part into CCM. |
| 2 | IN | power_in | Supply voltage input for a 4.5V to 16V input rail, decoupled by C1 and connected with a wide PCB trace. |
| 3 | SW | output | Switch output node, which must be connected with a wide PCB trace. |
| 4 | GND | power_in | System ground and reference for the regulated output voltage, to be connected to GND with copper traces and vias. |
| 5 | BST | passive | Bootstrap pin that requires a capacitor between SW and BST to form the floating high-side driver supply, with a 10Ω resistor between SW and the BST capacitor strongly recommended to reduce SW spike voltage. |
| 6 | EN/SYNC | input | Enable/synchronize pin: drive high to enable the regulator, and apply an external clock of 300kHz to 2MHz to change the switching frequency. |
| 7 | VCC | power_out | Internal 5V bias supply output that must be decoupled with a 0.1µF to 0.22µF capacitor placed close to the VCC and GND pins, not exceeding 0.22µF. |
| 8 | FB | input | Feedback input connected to the tap of an external resistor divider from the output to GND, with an internal 807mV feedback reference and frequency fold-back below 400mV. |
