CHANGE
On page 1, RC values on COMP pin in Figure 1A and 1B were both updated with values of 10k ? , 8.2nF, and 33pF.
On page 4, the pin description for Pin#4 was updated with new numbers to set boost switching frequency and
PFM mode.
In Table 2 on page 12, the FSW pin setting was updated with new numbers to set boost switching frequency and
PFM mode.
Initial Release.
