Automotive Power-Management IC with
Three Step-Down Converters and Linear Regulator
General Description
The MAX16920 power-management IC integrates
three high-voltage step-down DC-DC converters, one
high-voltage linear regulator, and an overvoltage
protection block. The three step-down converters deliver
up to 150mA, 600mA, and 1.5A, while the linear regulator
is capable of up to 150mA. The MAX16920 is designed
to operate with input voltages between 5.5V to 28V and
survive voltage transients to 45V, making it ideal for
automotive applications.
The MAX16920 is optimized for high efficiency and
low standby current. The MAX16920A features 400kHz
switching frequency, while the MAX16920B features
2MHz switching frequency. The MAX16920 can be
ordered with spread-spectrum frequency modulation.
The DC-DC converters can also be synchronized to
an external frequency reference using the SYNC input
minimize EMI.
The MAX16920 includes power-good outputs (PG_) for
DC-DC2, DC-DC3, LDOA, and a power-on reset ( POR)
for DC-DC1. All regulators other than DC-DC1 have
an enable input (EN_). DC-DC1 always operates when
power is applied to the MAX16920.
The MAX16920 operates over the -40°C to +125°C
temperature range, and is available in a compact,
thermally enhanced 32-pin TQFN package (7mm x 7mm).
