6.0 Overview
The LM10506 contains three buck converters and one LDO.
Table 1 and Table 2 below list the output characteristics of the
power regulators. They explain the function of the H/L pins for
B2 and B3 if tied High or Low at startup, and show the part's
behavior in standby. The tables also describe the SPI-pro-
grammable output voltage range for each buck regulator as
well as the maximum output current for the buck regulators
and LDO.
