800mA, Low-Noise, Step-Up DC-DC Converter
with 500mA Linear Regulator
ELECTRICAL CHARACTERISTICS (continued)
(VOUT = VPOUT = VINL = VONA = VONL = 3.6V, CLK/SEL = FBL = ONB = TRACK = PGND = GND, ISET = REF (bypassed with
0.22µF), LX = open, OUTL = open (bypassed with 4.7µF), TA = 0°C to +85°C, unless otherwise noted. Typical values are at
TA = +25°C.)
