HEERMICR · DC-DC Converters · SOT-23-6
HE9810M6R from HEERMICR, 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 | SW | output | Power switch output and drain of the internal MOSFET; connect the power inductor and output rectifier to SW, which can swing between GND and 24V. |
| 2 | GND | power_in | Ground pin for the regulator. |
| 3 | FB | input | Feedback input with a 0.6V feedback voltage; connect a resistor divider to FB to set the output voltage. |
| 4 | CE | input | Regulator on/off control input where high turns the converter on and low turns it off; when not used, connect it to the input supply for automatic startup. |
| 5 | VDD | power_in | Input supply pin that must be locally bypassed; the application note says it may connect to VOUT or VIN and recommends VOUT when VIN is below 5V. |
| 6 | RS | passive | Current-limit setting resistor pin, where RS = 25K/IL(A) sets the peak inductor current; RS must not be left floating and should be connected to GND if external current limiting is not used. |
