• Manufacturer: Freescale Semiconductor, Inc

Applications Information
devices that are needed externally in addition to the Linear Technologies devices. The con-
version efficiency is 89% and 93% for the LTC1147 and LTC1148, respectively. Figure 11-
2 and Figure 11-3 show the solutions provided by using the switching regulators. The
MAX767 provides over 90% conversion efficiency at less than $4 in 1000 piece quantities.
The MAX767 solution also requires discreet components off-chip. The MAX767 uses a
smaller inductor than the LTC1148 solution. Figure 11-4 shows a MAXIM voltage regulator
solutions. All the suggested solutions meets 3.3 V
