The EZ6301QI has three independent inputs/outputs: one 1.5 A switcher and two 300 mA LDOs. The EZ6303QI also has three independent inputs/outputs, but with one 2.2 A switcher and two 300 mA LDOs. The input voltage range for the switcher is 2.7 V to 6.5 V, and the LDO's input voltage range is 1.6 V to 6.5 V. Output voltage for the solutions is 0.6 V to 3.3 V.
