TPS92515QDGQRQ1 from Texas Instruments, in a MSOP-10-EP. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | COFF | input | Off-time programming pin. Connect a resistor from VOUT and a capacitor to GND to set the constant OFF-time (COFF threshold ≈ 1.00 V, tOFF(max) ≈ 230 µs). |
| 2 | VCC | power_out | 5 V internal regulator output (typ 5.0 V, 4.8-5.2 V, current limit ~19 mA). Requires a decoupling capacitor to GND; used to bias internal circuitry and can supply the BOOT diode. |
| 3 | GND | power_in | Device ground reference for control circuitry and VCC regulator return. |
| 4 | BOOT | input | Bootstrap supply for the high-side N-FET gate driver. Connect a ceramic capacitor between BOOT and SW and a diode from VCC to BOOT (BOOT-to-SW absolute max 5.5 V; BOOT-to-GND up to 50.5 V). |
| 5 | SW | output | Internal N-channel MOSFET source / switch node. Connect to the output inductor; swings between VIN and GND during switching. |
| 6 | DRN | input | Internal N-channel MOSFET drain. Connect externally to the CSN node (downstream of the current-sense resistor) to complete the high-side switch path. |
| 7 | CSN | input | Current-sense negative input. Connect the current-sense resistor from VIN to CSN for high-side peak current control (VCST peak threshold ≈ 240 mV when VIADJ = VCC). |
| 8 | VIN | power_in | Input supply pin (5.5 V to 42 V for TPS92515-Q1; also the current-sense positive input reference). VIN UVLO falling threshold ≈ 4.90 V. |
| 9 | PWM | input | PWM/UVLO dimming input. Drive with a PWM signal to pulse-width modulate the LED current from the analog-controlled maximum level; tie to VCC if unused (threshold ≈ 1.0 V, absolute max 5.5 V). |
| 10 | IADJ | input | Analog output-current adjust input (0.1 V to 2.2 V linear range, absolute max 5.5 V). Connect to an external divider or reference to scale peak current, or tie to VCC for full-scale operation. |
| PAD | Thermal pad | power_in | Exposed PowerPAD on package bottom. Connect to the GND plane for electrical ground and thermal dissipation (RθJC(bot) ≈ 5.3 °C/W). |
