The ROHS3 compliance means no exempt substances are sunsetting; the part ships with full TI material declaration. No PCN-driven respin risk from a RoHS exemption expiry. ## Supply range and topology flexibility The 15V to 90V Vcc range covers 24V and 48V industrial rails with margin — 48V nominal plus 20% transient sits at 57.6V, well inside the 90V abs-max. The controller also starts from a 15V bias rail, so a simple auxiliary winding or a small linear regulator can power it. Half-bridge and push-pull topology support means the same controller IC works for isolated and non-isolated designs. A half-bridge drives the primary of a transformer with a DC-blocking cap; push-pull uses a centre-tapped winding. Both are common in telecom brick converters and industrial auxiliary supplies. The function is Step-Up/Step-Down, which in this context means the controller regulates an output voltage that can be above, below, or inverted relative to the input — the actual conversion ratio depends on the transformer turns ratio and the duty cycle. ## Switching frequency and synchronous rectification The oscillator is programmable to 200kHz or 600kHz. At 200kHz the magnetics are larger but the switching losses are lower; at 600kHz the transformer and output inductor shrink by roughly 3× in volume, but the gate-drive losses and the dead-time accuracy become more critical. The clock sync input lets multiple LM5041s run from a single master oscillator, eliminating beat-frequency ripple in paralleled or multi-output designs. The synchronous rectifier output generates a complementary drive signal for the secondary-side FET. Replacing a Schottky catch diode with a low-Rds(on) FET typically recovers 3-5% efficiency in the 50-100W range, which matters for thermal management in a sealed enclosure. ## Control features and temperature grade Dead-time control, frequency control, and soft start are the three adjustments that shape the switching waveform. Dead-time prevents shoot-through in the half-bridge FETs; soft start limits the inrush current during startup; frequency control sets the oscillator timing. All three are accessible via external resistors and capacitors — no digital programming required. The -40°C to 125°C junction temperature range is the full industrial grade. The controller can sit in an outdoor telecom cabinet or a factory-floor enclosure without active cooling, as long as the total power dissipation stays within the package thermal limits. The 16-TSSOP package has a 4.4mm body width and 0.65mm pin pitch — a standard 4-layer board with 0.2mm traces and 0.3mm vias handles the fan-out. No exposed pad; thermal dissipation goes through the pins and the copper plane on the top layer. The part ships in a tube, not tape-and-reel.","metaTitle":"TI LM5041MTC/NOPB PWM Controller, 15-90V, 600kHz, 16-TSSOP","metaDescription":"Texas Instruments LM5041MTC/NOPB — active-production PWM controller, 15V to 90V supply, 200/600kHz switching, half-bridge/push-pull, 16-TSSOP.
