Microelectronics has
announced two new devices in a
growing family of Programmable
Power Manager (PPM) integrated
circuits (ICs). The
SMB110
and SMB113
continue a new concept in power
supply design that delivers
unparalleled flexibility and ease
of implementation to system
design engineers. Using Summit's
PPM IC's, system designers can
digitally program the entire
multiple output power supply and
associated power management
functions with a few clicks of a
mouse compared to the tedious
iterative hardware design of
conventional analog power
solutions.
Incorporating a level of
programmability, integration and
precision previously missing in
power management offerings, the
SMB110 and SMB113 integrate
precise power delivery and power
control in a single device. In
addition to simplifying the power
supply design, Summit's
configurable technology creates a
"power system platform" that
allows a significant degree of
hardware re-use. Original
equipment and original design
manufacturers (OEMs and ODMs) can
reduce their development time and
engineering investment and bring
consumer products to market
faster and more reliably.
The SMB110 five-channel and
SMB113 four-channel PPM IC's are
optimized for increasingly
complex consumer electronics
applications such as digital
cameras/camcorders (DSC/DCC),
DVD/MP3 portable media
players/recorders, global
positioning (GPS) receivers,
personal digital assistants
(PDA's), LCD/TFT TV's/monitors,
digital set-top boxes (STB) and
digital video recorders (DVR's)
as well as 3G "smart" mobile
phones.
"The SMB110 and SMB113
demonstrate Summit's continued
commitment to easing the burden
on today's power supply designers
and extends the leadership
created by the award-winning
SMB120." stated Abid Hussain,
Summit marketing director.
"Designers can now choose a range
of standard products to address
virtually any complex power
supply challenge while retaining
the configurable 'platform' that
makes Summit power management
solutions so easy to use."
The SMB110 comprises a total of
five channels of power
conversion: two pulse-width
modulated (PWM) DC-DC step-down
(buck) converters, one PWM DC-DC
step-up (boost) converter, one
PWM DC-DC inverting step-up/down
(buck/boost) converter, and one
low-dropout (LDO) linear
regulator. The SMB113 offers four
identical channels of PWM DC-DC
step-down (buck) converters. The
PWM channels on both devices are
digitally programmable for output
characteristics and monitoring,
including voltage output levels
to +/- 0.5% accuracy. Each array
of converters is well suited to
powering components commonly
found in digital consumer
electronics such as DSPs, Codecs,
embedded CPUs, LCD-TFT displays,
CCD imagers, LED backlighting,
motor drives and memory arrays.
The outputs are easily scalable
for output current due to
external MOSFET switches, further
enhancing the flexibility for
various system requirements.
Complementing the precise power
regulation is a suite of advanced
power control features including:
Static or dynamic output voltage
programming and margining,
independent channel
sequencing/enable, and output
slew rate control. Additionally,
the devices provide complete
power system diagnostics,
including input and output
monitoring for under/over-voltage
(UV/OV), low/missing battery
detection, AC adapter detection
and RESET/HEALTHY output. The
margining function can be
conveniently used as an LED
backlight brightness or
audio-level control. The flexible
control capability also enables
more sophisticated power
management algorithms to boost
power efficiency and battery
lifetime in an increasingly
mobile product mix.
Programming
is achieved via the convenient
I2C bus and configuration data is
safely stored in non-volatile
EEPROM memory of which 96 bytes
are available for user data
storage. The devices can be
programmed during development and
then used in a "fixed"
configuration or they may be
re-programmed in-system via the
I2C interface.
Packaging, Pricing, and
Availability
The SMB110 and SMB113 PPM devices
operate directly from +2.7V to
+6.0V input, making it ideally
suited for one-cell Li-Ion
battery applications. Higher
input voltages (two-cell Li-Ion
or +12V) can be accommodated in
many cases with simple
applications configuration. The
operating temperature range is
+0C to +70C and packaging is the
5mm X 5mm 32-pad QFN-32 that is
lead-free and RoHS-standard
compliant. Available now in
production quantities, the SMB110
and SMB113 are both priced at
$2.60 each in quantities of 1,000
units.
Design Software and Programmer
for Prototype Development
To speed user product
development, Summit offers
customers the SMB110EV and
SBM113EV companion evaluation
boards providing a graphic user
interface (GUI) software so
designers can quickly see the
features and benefits and design
a prototype power supply with the
SMB110 or SMB113. This is a
complete development tool that
lets designers easily manipulate
the characteristics of their
systems. The SMB110EV and
SMB113EV design kits includes
menu-driven Microsoft
Windows® graphic user
interface (GUI) software to
automate programming tasks and
also includes all necessary
hardware to interface to the
parallel or USB port of a laptop
or PC.
Once a user completes design and
prototyping, the SMB110EV and
SMB113EV kits automatically
generate a HEX data file that can
be transmitted to Summit for
review and approval. Summit then
assigns a unique customer
identification code to the HEX
file and programs the customer's
production devices prior to final
electrical test operations. This
ensures that the device will
operate properly in the end
application. The design kit
software can be downloaded today
from Summit's website
(www.summitmicro.com).
