# LMR16006YQ5DDCRQ1

**Texas Instruments** · DC-DC Converters · TSOT-23-6

LMR16006YQ5DDCRQ1 from Texas Instruments, in a TSOT-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 | CB | input | Switch FET gate bias voltage pin; connect the Cboot capacitor between CB and SW, with CB to SW recommended at -0.3 V to 6 V (absolute maximum 7 V). |
| 2 | GND | power_in | Ground connection. |
| 3 | FB | input | Feedback input that sets the output via VOUT = VFB (1 + R1/R2), with recommended FB range 0 V to 5.5 V (absolute maximum 7 V). |
| 4 | SHDN | input | High-voltage-tolerant enable/disable input with internal pull-up current source; pull below 1.25 V to disable, float to enable, and use a two-resistor divider for input undervoltage lockout (recommended 0 V to 40 V, absolute maximum 65 V). |
| 5 | VIN | power_in | Power input voltage pin supplying the internal circuitry and serving as the drain node input for the internal high-side MOSFET; recommended range 4 V to 40 V, absolute maximum 65 V. |
| 6 | SW | output | Switch node that connects to the inductor, catch diode, and Cboot capacitor; recommended SW to GND range -1 V to 40 V (absolute maximum 60 V). |
