NDP3315SG-1

NDP · DC-DC Converters · SOT-89-5

NDP3315SG-1 from NDP, in a SOT-89-5. 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 SW output Drain of the internal NMOS switch; SW to GND is rated -0.3 V to VIN+0.3 V in the absolute maximum ratings.
2 GND power_in Ground reference for the device; the datasheet gives no separate voltage limit for this pin.
3 DIM input PWM/analog dimming input with an internal weak pull-up; driving DIM below 0.3 V turns the output off, and DIM to GND is rated -0.3 V to +6.5 V.
4 CSN input Current-sense input, referenced to VIN, used to measure output current across the external sense resistor; VIN, CSN to GND is rated -0.3 V to 36 V.
5 VIN power_in Power input with a 6 V to 30 V operating range per the electrical characteristics; VIN, CSN to GND is rated -0.3 V to 36 V.
