Frequently Asked Questions
How much output current can the LM2598T-3.3 deliver?
The LM2598T-3.3 is rated for up to 150mA continuous output current. It features built-in current limiting and thermal shutdown to protect against overload conditions, making it suitable for low-power 3.3V rail applications in embedded systems.
Which input voltage range does the LM2598T-3.3 support?
The LM2598T-3.3 operates from an input voltage of 4V up to 40V, providing wide input flexibility. This makes it useful for 5V, 12V, or 24V bus systems as well as automotive and industrial applications where supply voltages can vary significantly.
What external components are required with the LM2598T-3.3?
Because the output voltage is fixed at 3.3V, no external feedback resistors are needed. A typical application requires only an inductor (100µH recommended), an output capacitor, an input capacitor, and a catch diode (e.g., 1N5822), keeping the BOM minimal and the PCB layout simple.
Can the LM2598T-3.3 be used in automotive designs?
Yes. With an input range up to 40V, a –40°C to +125°C operating temperature range, and a robust TO-263-5 surface-mount package, the LM2598T-3.3 meets typical automotive supply requirements. Always verify PPAP/AEC-Q100 qualification needs with Texas Instruments for safety-critical applications.
What are common alternatives to the LM2598T-3.3?
Pin- and function-compatible alternatives include the LM2596T-3.3 (3A output version from TI), the MC34063A (higher-frequency, up to 1.5A, popular low-cost option), and the NCV8870 from onsemi. For higher efficiency, consider the TPS54331 or LM46002 if PCB space allows a different footprint.
