FN7641.1
On page 6 - Electrical Spec Table VIN SUPPLY, changed "Standby Supply Current" to "ShutDown Supply Current"
and changed Symbol "IQ_SBY" to IIN_SD
On page 7 - Electrical Spec Table SYNCHRONIZATION, changed Symbol "VOH" to "VIL"
On page 12 - Added Efficiency Boost Buck performance Curve
Updated Equation 31 on page 19 by adding C3 to the equation, which was missing.
Deleted following sentence from last paragraph of “Power Stage Transfer Functions” on page 19: “A capacitor
(<1nF) at the FB pin to ground also helps proper PFM mode operation".
April 26, 2012
Added typical electrical specification of EN pull-up current and Synchronization on page 7.
Added boost-buck efficiency curve and “AUXVCC Switch-Over” on page 13.
Under “Output Voltage” on page 14 description, changed “(1/Fs tMINOFF)” To “ (1 - Fs * tMIN(OFF))”.
Under “Boost Converter Operation” on page 14, changed "(VIN*IIN = VOUT*IOUT*Efficiency)" to "(VIN*IIN =
