TPS54340DDAR
Brand: Texas Instruments
The TPS54340DDAR is an Eco-mode non-synchronous buck converter with an adjustable 100 kHz to 2.5 MHz switching frequency and a synchronizable clock input, delivering 3.5 A from a 4.5 V to 42 V input through a 92 mΩ integrated high-side MOSFET. It fits industrial 24 V/36 V bus point-of-load designs, including multi-rail systems that need frequency synchronization to avoid beat noise.
