APW7212 Overview
The device allows use of small inductors and output capacitors for portable devices. The current-mode control scheme provides fast transient response and good output voltage accuracy. At light loads, the APW7212 will automatically enter in pulse frequency modulation(PFM) operation to reduce the dominant switching losses.
