Efficiency: 86 - 87% @ Iout=1.35A Vout=3.3V Vin=12V and 5V 

No load output ripple (AC coupling), Vin = 12V, Vout = 3.3V
Output ripple @ 330mA output current, Vin = 12V, Vout = 3.3V, Rload = 10R
Output ripple @ 1.65A, Vin = 12V, Vout = 3.3V, Rload = 2R
Output voltage transient response (AC coupling) 0 to 1.65A, Vin = 12V, Vout = 3.3V
Output voltage transient response 0 to 330mA, Vin = 12V, Vout = 3.3V
