DX2980
Dersem · DC-DC Converters · SOT-23-6
DX2980 from Dersem, in a SOT-23-6. 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 | BST | passive | Bootstrap pin: connect a capacitor between SW and BST to form a floating supply across the power switch driver that drives the switch gate above the supply voltage (BST to GND limited to VSW-0.3 to VSW+6 V). |
| 2 | GND | power_in | Ground and voltage reference for the regulated output voltage; requires special layout care and isolation from the D1 to C1 ground path to prevent switching current spikes. |
| 3 | FB | input | Feedback input that sets the output voltage from an external resistor divider (0.812V typical reference), with the oscillator frequency foldback active when FB is below 250mV. |
| 4 | EN | input | On/Off control: pull EN above 1.35V to turn the device on, or connect to VIN through a 0.1MΩ resistor for automatic enable. |
| 5 | VIN | power_in | Supply voltage input, 5.0V to 80V operating (85V absolute maximum), requiring input capacitor C1 to prevent large voltage spikes at the input. |
| 6 | SW | output | Power switching output, the drain of the N-channel power MOSFET, supplying power to the output LC filter (-0.3V to VIN+0.3V). |
