LM5041BMTCX

Texas Instruments · DC-DC Converters · TSSOP-16

LM5041BMTCX 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 Input voltage to the start-up regulator operating over 15V to 100V range.
2 FB input Inverting input to the internal error amplifier with 0.75V reference on the non-inverting input.
3 COMP output Internal error amplifier output with active sink capability (10mA max), 5kΩ pull-up, and 0.1µF bypass capacitor requirement.
4 REF power_out Precision 5V regulated reference output (max 10mA current) staying low until VCC UVLO is satisfied.
5 HD output Main buck stage PWM control output with duty cycle clamp ensuring 240ns minimum off-time per cycle.
6 LD output Buck synchronous switch PWM control output providing HD inversion during normal operation.
7 VCC power_out Regulated 9V output from the internal high-voltage start-up regulator.
8 PUSH output Push-pull gate driver output with 1.5A peak capability.
9 PULL output Push-pull gate driver output with 1.5A peak capability.
10 PGND power_in Power ground connection.
11 AGND power_in Analog ground connection.
12 CS input Current sense input to the PWM comparator with 50ns leading edge blanking and 0.5V cycle-by-cycle current limit threshold.
13 SS input Soft-start control input with 10µA internal charge source that forces HD and LD low below 0.45V shutdown threshold.
14 TIME input Push-pull overlap/dead-time control pin with external resistor providing overlap when connected to GND or dead-time when connected to REF.
15 RT input Oscillator frequency timing pin with external resistor that accepts external clock signals (>3V peak, 15-150ns width) for synchronization.
16 UVLO input Line under-voltage lockout pin with external resistor divider setting 2.5V shutdown threshold and 20µA hysteresis current.
