ICW3150ASPG from ICW, in a ESOP-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 | NC | unconnected | No connect. Leave floating. |
| 2 | SW | output | Power MOSFET switching output. Connects to the external inductor and Schottky freewheeling diode of the buck converter. Absolute maximum voltage -0.3V to VIN. |
| 3 | GND | power_in | Ground reference for the IC. |
| 4 | FB | input | Voltage feedback pin. Senses output voltage via an external resistor divider. Internal reference is 1.25V; Vout = 1.25 × (1 + R2/R1). |
| 5 | CS | input | Current-sense pin for constant-current loop feedback. Senses the voltage drop across an external Rcs (typical CS threshold ~118 mV). Tie to GND when only the CV loop is used. |
| 6 | NC | unconnected | No connect. Leave floating. |
| 7 | VC | passive | Internal LDO bypass capacitor pin. Connect a bypass capacitor (typ. 1nF, adjustable 1~4nF for CC-loop stability) between VC (pin 7) and VIN (pin 8). |
| 8 | VIN | power_in | Input supply pin. Wide operating range 8V to 36V (absolute max 45V). Bypass to GND with 100µF/50V bulk plus 1µF (105) ceramic near the pin. |
| 9 | EP | power_in | Exposed thermal pad on package underside. Per the pin table, the backside pad is tied to the SW node (pin 2). Solder to a copper thermal-relief plane sized for heat dissipation; do NOT connect to GND. |
