# TPS92515QDGQTQ1

**Texas Instruments** · LED Drivers · MSOP-10-EP

TPS92515QDGQTQ1 from Texas Instruments, in a MSOP-10-EP. 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 | COFF | input | Connect a resistor from VOUT and a capacitor to GND to set the OFF-time. |
| 2 | VCC | power_out | 5-V regulator output; use a decoupling capacitor from VCC to ground (see the VCC capacitor selection section). |
| 3 | GND | power_in | Ground. |
| 4 | BOOT | input | Connect a ceramic capacitor between BOOT and SW and a diode from VCC to BOOT to power the high-side FET drive circuitry. |
| 5 | SW | output | Internal FET source; connect to the output inductor. |
| 6 | DRN | input | Internal FET drain; connect to the CSN node. |
| 7 | CSN | input | Current sense negative input; connect the current sense resistor from VIN to CSN for high-side current sense control. |
| 8 | VIN | power_in | Connect to input voltage (recommended operating VIN is 5.5 V to 42 V for TPS92515x and 5.5 V to 65 V for TPS92515HVx); VIN is also the current sense positive input. |
| 9 | PWM | input | PWM dimming input; output current is PWM dimmed from the maximum analog controlled level, and it should be connected to VCC if not used. |
| 10 | IADJ | input | Output current adjust; connect to an external divider or reference, or tie to VCC, with the internal clamp at 2.4 V. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
