TPS92512HVDGQR 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 | BOOT | output | Bootstrap capacitor node. Connect a bootstrap capacitor between BOOT and PH to develop gate drive for the internal high-side MOSFET. If the BOOT-PH voltage falls below the BOOT UVLO (~2.25V rising / 1.99V falling), the output switch is forced off until the capacitor recharges. Absolute max: (PH + 8) V; sink current limit 1 mA. |
| 2 | VIN | power_in | Input supply voltage pin. Operating range 4.5V to 42V (TPS92512) or 4.5V to 60V (TPS92512HV). Absolute max 45V (65V for HV). Bypass with a low-ESR ceramic capacitor close to the pin. |
| 3 | UVLO | input | Adjustable undervoltage lockout input. Set the rising VIN turn-on threshold with a resistor divider from VIN. Internal rising threshold is 1.22V (typ); pin sources ~3.97 µA when enabled and ~1.05 µA when disabled to provide hysteresis. Absolute max 5V. |
| 4 | PDIM | input | PWM dimming input. The duty cycle of the applied PWM signal linearly modulates the average LED output current (10:1 and 100:1 dimming ratios supported). Compatible with low-voltage logic; absolute max 5V. |
| 5 | RT/CLK | bidirectional | Resistor timing and external clock input. A resistor to GND programs the switching frequency (100 kHz - 2 MHz in RT mode). If pulled above the PLL upper threshold, the pin becomes a high-impedance clock input for synchronization (300 kHz - 2 MHz, min pulse 51 ns); the internal RT amplifier is disabled. If clock edges stop, the amplifier is re-enabled and the mode reverts to the resistor-programmed frequency. Absolute max 3.6V. |
| 6 | IADJ | input | Analog current adjust input. Voltage applied here (0.18V to 1.8V linear range; clamped ~1.8-2.77V) programs the ISENSE current-sense threshold as VIADJ/6, yielding a 30 mV to 300 mV sense range for 0-300 mV adjustable LED current control. Absolute max 3V. |
| 7 | ISENSE | input | Inverting input of the transconductance (gM) error amplifier and current-sense feedback. Connect to the top of the LED-current sense resistor; the loop regulates VISENSE to VIADJ/6. Input bias ~20 nA; absolute max 3V. |
| 8 | COMP | output | Error-amplifier output and input to the peak-current PWM comparator. Connect the frequency-compensation network (typically a series R-C to GND) here. Transconductance gain ~331 µA/V, DC gain ~10 kV/V, bandwidth ~2.7 MHz; source/sink capability ±28 µA. Absolute max 3V. |
| 9 | GND | power_in | Device ground return. Tie directly to the exposed PowerPAD and to the system ground plane with a low-inductance connection. |
| 10 | PH | output | Switch node; source of the internal high-side N-channel MOSFET (RDS(on) ~200-232 mΩ). Connect to the external inductor and to the bootstrap capacitor lower plate. Absolute max 45V (65V for HV); −0.6V DC, −2V for 10-ns transients. |
| PAD | PowerPAD | power_in | Exposed thermal/ground pad on the package bottom. Must be electrically connected to the PCB ground plane directly beneath the device for proper electrical and thermal operation. Voltage difference to GND: ±200 mV max. |
