SNVSA70 – FEBRUARY 2015 LP8728B-Q1 Quad-Output Step-Down DC-DC Converter
1 Features 3 Description The LP8728B-Q1 is a quad-output Power
Management Unit (PMU), optimized for low-power
FPGAs, microprocessors, and DSPs for automotive
applications. This device integrates four highly
efficient step-down DC-DC converters into one
package. Each converter has high current capability
and separate controls which allows flexibility to use
the device in multiple applications. All the converters
operate above the AM band with a fixed 3.2-MHz
switching frequency. The high-side switch turn-on
time of each converter is phase shifted to minimize
input current spikes. 1 LP8728B-Q1 is an Automotive Grade Product that
is AECQ-100 Grade 1 Qualified
Four High Efficiency Step-Down DC-DC
Converters:
– 93% Peak Efficiency (VIN = 5 V, VOUT = 3.3 V) …
