NCP3064BMNTXG
onsemi · DC-DC Converters · DFN-8-EP(4x4)
NCP3064BMNTXG from onsemi, in a DFN-8-EP(4x4). 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 | Switch Collector | output | Internal Darlington switch collector, rated −0.3 V to 42 V and switching a peak current of up to 1.5 A. |
| 2 | Switch Emitter | output | Internal Darlington switch emitter, rated −0.6 V to VCC when the transistor is off, measured versus pin 4. |
| 3 | Timing Capacitor | passive | Timing capacitor node for the oscillator, with pin voltage limited to −0.2 V to +1.4 V and CT charged and discharged in a 6:1 current ratio. |
| 4 | GND | power_in | Ground pin for all internal circuits, to which all maximum ratings are referenced; the EP flag must be tied to this pin on the PCB. |
| 5 | Comparator Inverting Input | input | Inverting input of the internal comparator, rated −0.3 V to VCC. |
| 6 | VCC | power_in | Voltage supply pin, rated −0.3 V to 42 V, with a specified input voltage range of 3.0 V to 40 V. |
| 7 | Ipk Sense | input | Peak current sense input that monitors the voltage drop across an external resistor to limit peak switch current, rated −0.3 V to (VCC + 0.3 V). |
| 8 | ON/OFF | input | Enable pin where a high level (above about 1.4 V, up to 25 V max) runs the device and a low or floating level puts it in low-power standby, rated −0.3 V to 25 V and below VCC. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
