LM5041MTCX

Texas Instruments · DC-DC Converters · TSSOP-16

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.
