AS3729B − Typical Operating Characteristics

Figure 7:

Efficiency vs. Output Current for 2016 Coil Types

Figure 8:

Efficiency vs. Output Current for 2520 Coil Types

AS3729B Step Down DC/DC: Shows the

Efficiency of AS3729B of various coil

types in a 2016 package in dual and

combined mode. For the dual mode two

1uH coils are used and for the combined

mode one 470nH coil. VSUP = 3.7V,

VOUT = 1.2V, 1.35MHz operation,

TA = 25°C
