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 | VIN | power_in | Source input voltage for the start-up regulator; input range 15V to 100V. |+| 2 | FB | input | Feedback signal, inverting input for the internal error amplifier with 0.75V reference on non-inverting input. |+| 3 | COMP | output | Output of the internal error amplifier with internal 5kΩ resistor pull-up and active sink capability. |+| 4 | REF | output | Precision 5V reference output with maximum output current of 10mA; decoupled with 0.1µF capacitor locally; stays low until line and VCC under-voltage lockout are satisfied. |+| 5 | HD | output | Main buck PWM control output with maximum duty cycle clamp corresponding to typical 240ns off-time per cycle. |+| 6 | LD | output | Synchronous switch control output, inversion of HD output. |+| 7 | VCC | power_out | Regulated 9V output from internal high-voltage start-up regulator; shuts down regulator if auxiliary winding raises voltage above setpoint. |+| 8 | PUSH | output | Output of the push-pull gate driver with 1.5A peak output capability. |+| 9 | PULL | output | Output of the push-pull gate driver with 1.5A peak output capability. |+| 10 | PGND | power_in | Power ground connected directly to analog ground. |+| 11 | AGND | power_in | Analog ground connected directly to power ground. |+| 12 | CS | input | Current sense input to PWM comparator with 50ns leading edge blanking; exceeding 0.5V initiates cycle-by-cycle current limit; exceeding 0.6V disables outputs and starts soft-start. |+| 13 | SS | input | Soft-start control input with external capacitor and internal 10µA current source; controller enters low power state if below 0.45V shutdown threshold. |+| 14 | TIME | input | Push-pull overlap and dead time control input; external resistor to GND produces overlap time; external resistor to REF produces dead time. |+| 15 | RT/SYNC | input | Oscillator timing resistor input that sets oscillator frequency; also accepts external oscillator signal. |+| 16 | UVLO | input | Line under-voltage lockout input; external divider sets shutdown levels with 2.5V threshold; hysteresis set by switched internal 20µA current source. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-16 |+| Category | Power Management (PMIC) |+| Pins | 16 |++## CAD (KiCad official)++- Symbol: `LM5041MTCX`+- Footprint: `Package_SO:TSSOP-16_4.4x5mm_P0.65mm`+- 3D model: TSSOP-16 (KiCad packages3D, STEP)+- 3D model files: `lm5041mtcx-etched.step` / `lm5041mtcx-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lm5041mtcx.step` / `lm5041mtcx.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/lm5041) (24 pp, sha256 `6517ff639681fa1c`, retrieved 2026-09-26, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.2`, primary `claude-haiku-4-5-20251001` (text), consensus `claude-sonnet-4-6` (agreed), guards: pin_guards 0.1: passed.
