PAM2401SCADJ from Diodes Incorporated, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | LX | passive | Switch node. Connects to the drain of the internal N-channel MOSFET and source of the P-channel synchronous rectifier; the external boost inductor ties from VIN to this pin. |
| 2 | EN | input | Enable control input. VH ≥ 1.5V (VIN=3.3V) or ≥ 0.8V (VIN=0.9V) turns the converter on; VL ≤ 0.2V (VIN>1.2V) puts the part into <1µA shutdown. |
| 3 | VIN | power_in | Input supply pin, 0.9V to 4.75V operating range (absolute max +6.0V). Bypass with at least a 10µF ceramic capacitor located close to the IC. |
| 4 | AGND | power_in | Analog ground. Reference for the control circuitry; connect to the system ground plane. |
| 5 | FB | input | Feedback pin, internally regulated to 0.6V. Connect the tap of an external resistor divider from VOUT to set the output voltage per VOUT = 0.6 × (1 + R1/R2). |
| 6 | RSET | input | Programmable current-limit setting pin. An external resistor to GND selects the N-channel current limit (e.g. 66kΩ → 1A, 100kΩ → 1.5A, floating or >200kΩ → 3A). |
| 7 | OUT | power_out | Regulated boost output pin, adjustable 2.5V to 5.0V. Also senses the output for the true-disconnect P-MOSFET and internal OVP/PG comparators; bypass with a minimum 22µF ceramic capacitor. |
| 8 | PGND | power_in | Power ground return for the internal N-channel switch. Connect with a low-impedance path to the input and output capacitor grounds. |
