PF4210
14-channel power management integrated circuit (PMIC) for audio/video applications
[1] When output is set to > 2.6 V, the output follows the input down when VIN gets near 2.8 V.
[2] The higher output voltage available depends on the voltage drop in the conduction path as given by the following equation: (VINSW2 − VSW2) = ISW2* (DCR
of Inductor + RONSW2P + PCB trace resistance).
