Its 15V to 90V supply range means it can connect directly to a 48V telecom bus, a 72V industrial rail, or a 24V battery bank without an intermediate regulator — that wide Vcc window simplifies the front-end design and reduces component count. ## Switching frequency and synchronous rectification The oscillator is programmable to either 200kHz or 600kHz — the lower frequency keeps switching losses down in a high-voltage step-down, while 600kHz shrinks the magnetics for a compact board layout. Clock sync input is available to lock the switcher to an external clock, avoiding beat-frequency noise in multi-rail systems. Synchronous rectification is built in, so the controller drives both the main switch and the SR FET. This recovers the body-diode conduction loss that would otherwise dominate at low output voltages — expect a few points of efficiency gain over a diode-rectified design, especially at 3.3V or 5V outputs. ## Thermal and package considerations for the layout Control features include dead-time control, frequency control, and soft-start — the dead-time adjustment lets you tune the non-overlap interval between the main switch and the SR FET, which directly affects shoot-through margin and light-load efficiency. Note that the device is marked RoHS non-compliant — if your BOM requires RoHS exemption or a fully compliant alternative, confirm the assembly house's policy on lead-bearing terminations before committing the board.","metaTitle":"Texas Instruments LM5041ASD PWM Controller, 15-90V","metaDescription":"Active PWM controller from TI, 15V to 90V supply, step-up/step-down topology, 200/600kHz switching, synchronous rectification, -40 to 125°C.
