(1) The default output voltage and switching frequency of this EVM are 5 V and 1 MHz, respectively. The VLDOIN pin conencts to the output for output voltages of 3.3 V and above. Efficiency and other performance metrics can change based on operating input voltage, load current, switching frequency, external bias voltage, ambient temerature, externally connected output capacitance, and other parameters.
(2) The recommended airflow is 200 LFM when operating at output currents greater than 4 A and switching freqeuncies above 1 MHz.
(3) Configure the EVM as an IBB topology with negative output voltage by connecting the input source between the VIN+ and VOUT+ power terminals. The achievable output current is IOUT = ILmax(DC) × (1 – D), where ILmax(DC) = 6 A is the rated DC current of the integrated inductor of the module and D = |VOUT| / (VIN + |VOUT|) is the duty cycle.
