DESCRIPTION
Initial release
Changed R_FOSC = 120kI to R_FOSC =66.5kI in the Electrical Characteristics
globals and table; changed the min, typ, max values for R_FOSC from 190kHz
(min), 220kHz (typ), 250kHz (max) to 360kHz (min), 400kHz (typ), 444kHz (max);
changed the minimum on-time (t_{ON_MIN}) from 80ns (typ) to 110ns (typ); updated the
GAIN_MOD(DC) and f_pMOD equations; removed future status from the 16-pin TQFN
package in the Ordering Information table
Added two new OPNs in the Ordering Information table
