NDP1335KC from NDP, in a SOP-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 | FB | input | Feedback input for the output voltage, referenced to the internal 1.0V reference (VREF 0.985V to 1.015V) with a FB bias current of 0.2µA. |
| 2 | CSP | input | Positive pole of the current sense; the current-sense amplifier threshold VCS (CSP-CSN) is specified at 57 to 63mV. |
| 3 | CSN | input | Negative pole of the current sense; the sense voltage is measured as CSP-CSN, and CSP/CSN to GND is rated -0.3V to 25V. |
| 4 | VIN | power_in | Power input, specified for 7V to 30V operation with an absolute maximum of 33V to GND and an overvoltage protection threshold of 32V. |
| 5 | SW | output | Switching node connected to the inductor; SW to GND is rated -0.3V to VIN+0.3V. |
| 6 | SW | output | Switching node connected to the inductor (same net as pin 5); SW to GND is rated -0.3V to VIN+0.3V. |
| 7 | FS | passive | Connect a resistor to GND to set the switching frequency (floating gives 130kHz, 470kΩ to GND gives 300kHz); pulling below 0.3V shuts the device down. |
| 8 | GND | power_in | Ground reference for the device. |
