# TPS92515DGQR

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

TPS92515DGQR 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 | OFF-time setting node; connect a resistor from VOUT and a capacitor to GND to set the OFF-time. |
| 2 | VCC | power_out | Regulated 5-V supply output from internal voltage regulator; connect a decoupling capacitor from VCC to ground. |
| 3 | GND | power_in | Ground reference and power return. |
| 4 | BOOT | input | Bootstrap supply input for high-side FET gate drive; connect a ceramic capacitor between BOOT and SW and a diode from VCC to BOOT. |
| 5 | SW | output | Internal FET source node; connect to output inductor. |
| 6 | DRN | input | Internal FET drain node for current sensing; connect to CSN node for high-side current measurement. |
| 7 | CSN | input | Current sense negative input; connect current sense resistor from VIN to CSN for high-side peak current control. |
| 8 | VIN | power_in | Main input voltage supply (5.5 V to 42 V for TPS92515) and current sense positive reference. |
| 9 | PWM | input | Pulse-width modulation dimming input; output current is PWM dimmed from maximum analog controlled level, or connect to VCC if not used. |
| 10 | IADJ | input | Analog current adjust input; connect to external divider, reference, or tie directly to VCC. |
| 11 | Thermal pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
