# MAX662ACSA+T

**Maxim Integrated** · DC-DC Converters · SO-8

MAX662ACSA+T from Maxim Integrated, in a SO-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 | C1- | passive | Negative terminal for the first charge-pump capacitor, which should be a 0.22µF to 1.0µF ceramic or tantalum type. |
| 2 | C1+ | passive | Positive terminal for the first charge-pump capacitor, which should be a 0.22µF to 1.0µF ceramic or tantalum type. |
| 3 | C2- | passive | Negative terminal for the second charge-pump capacitor, which should be a 0.22µF to 1.0µF ceramic or tantalum type. |
| 4 | C2+ | passive | Positive terminal for the second charge-pump capacitor, which should be a 0.22µF to 1.0µF ceramic or tantalum type. |
| 5 | VCC | power_in | Supply voltage input, specified for 4.5V to 5.5V operation. |
| 6 | VOUT | power_out | Regulated +12V output (±5%) rated for 30mA guaranteed, which equals VCC when the part is in shutdown. |
| 7 | GND | power_in | Ground reference pin, which must be connected to SHDN for normal operation. |
| 8 | SHDN | input | Active-high CMOS-logic shutdown input, internally pulled up to VCC, which halts the charge pumps and connects VOUT to VCC when high. |
