LM5041MTCX from Texas Instruments, in a TSSOP-16. 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. |
