Texas Instruments LM5181 | Demoboard PMP31177

Beschreibung

This 26.54 mm × 11.68 mm × 5.6-mm height board is optimized to leverage the performance of the LM5181 PSR Flyback converter. The board operates over an input voltage range of 18 V to 32 V to deliver a 24-V and 3.3-V outputs at currents up to 40 mA and 15 mA, respectively. Operating without an auxiliary winding or optocoupler, the LM5181 provides very tight output voltage regulation. The LM5181 offers several protection features, like undervoltage lockout to provide proper operation during voltagesag conditions, programmable soft-start to reduce inrush current, hiccup-mode overcurrent protection, and thermal shutdown.
