Full-load efficiency(2) CH1, VOUT1 = 5-V, VIN = 12-V, IOUT1 = 3-A 91.2%
CH1, VOUT1 = 5-V, VIN = 24-V, IOUT1 = 3-A 89.6%
CH2, VOUT2 = 3.3-V, VIN = 12-V, IOUT2 = 3-A 87.5%
CH2, VOUT2 = 3.3-V, VIN = 24-V, IOUT2 = 3-A 85.5%
(1) Default output voltages and switching frequency are 5-V (CH1), 3.3-V (CH2) and 1 MHz, respectively.
(2) The recommended airflow is 200 LFM when operating
(3) The EVM operates when the input voltage is in the range of 3-V to 6-V, but enters a dropout mode if there is insufficient input voltage to regulate output voltages.
