Power management ICs for ARM multicore
processor chips
Dialog Semiconductor plc has launched advanced system
level power management ICs (PMICs) for tablet PCs, smartphones,
embedded computers and multimedia players. The new DA9053
and DA9021 devices support major mobile graphics and application
processor families.
The DA9053 becomes Dialog's flagship system level PMIC
for high-end multicore-based applications and supports the
ARM Cortex family whilst the DA9021 addresses lower power
cost-sensitive applications.
"Dialog's latest generation PMICs extend the company's
leadership in configurable system power management via multicore
support," said Udo Kratz vice president and general
manager of Dialog's audio and power management business
unit. "Through our Processor Partner Programme we have
already gained multiple design wins across a broad range
of applications and expect the first DA9053 based consumer
devices to be on store shelves around Q3 of this year."
The DA9053 provides multi-processor core power and delivers
power-up flexibility with energy efficiency. It combines
a 1.8A rated dual-input DC/USB power path router with a
switching battery charger and includes support for multiple
external memory configurations. The DA9053 is suggested
for designing power supply circuit in the latest generation
media and wireless computing applications, such as tablet
PCs.
The DA9021 includes a 1.3A single input USB charger and
its internal regulators deliver approximately half the total
current relative to DA9053.
"In 2009 we launched the DA9052, the world's first
easily configurable system PMIC; since then there has been
a rapid growth in the portable device market, especially
for tablet PCs and e-readers. Dialog's third generation
of PMICs have been designed with these systems specifically
in mind, continuing such innovation. The DA9053 and DA9021
devices, with their advanced feature sets and performance,
will enable manufacturers to easily get new, perfectly power-optimised
consumer devices to market," concluded Kratz.
The DA9053 is supplied in a 169 ball VFBGA 7 x 7mm package
with 0.5mm pitch or VFBGA 11x11mm package with 0.8mm pitch
and is available in both consumer and automotive grades.
The DA9021 is supplied in a 64 ball 4 x 4mm wafer-level
package with 0.5mm pitch. Samples of both the DA9053 and
the DA9021 are available immediately.
Companies supported by Dialog's Processor Partner Programme
include Freescale, Marvell, Renesas (NEC) and Samsung.
