| LM27403 |
This LM27403EVM power management development kit from Texas Instruments is the best tool during the design phase. Its output produces a current of 25000 mA. This part has single output. This part is 91 % efficient. You can operate this at a switching frequency of 250 KHz.
Dev Kit Description
The LM27403 EVM is a 300-kHz, high efficiency, synchronous buck converter with voltage-mode control and inductor DCR current sensing for overcurrent protection. An inexpensive 2N3904 BJT is used to sense temperature at the inductor. This enables correction for the inductor DCR’s variation over temperature as well as provide a thermal shutdown function based on a desired temperature setpoint.
