Summit SMB206A, SMB210A Dual 3A and Single 6A Programmable Integrated Buck Regulators Deliver Flexible, High-Efficiency Power
Digital control for advanced power management of SoC's while high integration reduces size, cost and time-to-market for 'green' consumer electronics
Sunnyvale, Calif. - Summit Microelectronics has expanded its family of programmable DC-DC integrated circuits with the SMB206A and SMB210A. These new products bring cost-effective digital power control to high-volume digital consumer systems as well as general purpose applications.
Like the entire SMB20X family, the SMB206A and SMB210A support advanced power management for "green" and ENERGY STAR® applications. These include a wide range of multimedia consumer and broadband/SoHo applications such as digital LCD/LED/plasma/IP televisions, digital cable/satellite/IP set-top boxes and media gateways, broadband cable/DSL modems, wireless SoHo routers and switches.
The SMB206A/SMB210A are dual/single-output integrated DC-DC buck regulators combining Summit's digital programmability with dense integration, ultra-compact size, and cost-effective bill-of-materials (BoM) necessary for mass-market consumer products. With a serial digital interface and on-board non-volatile memory, the SMB20X family can be easily configured during development and re-programmed in system by host software. The result is a flexible, digitally controlled power supply design that is easily customizable without tedious hardware design cycles or complex microcontroller-style GPIO-based control. They can also be programmed by fixed resistors and purchased as standard products with fixed voltages. The integration of advanced power control functions eliminates external components and cost, improves functionality and performance, and minimizes development time.
"Summit continues to expand its line of programmable power products with the SMB206A and SMB210A DC-DC regulators," stated Abid Hussain, Summit vice-president of marketing and applications. "The unprecedented combination of flexibility, integration, reduced BoM and solution size brings true digital power management to high-volume, cost-sensitive consumer applications and enables advanced power-saving techniques to meet stringent ENERGY STAR and other "green" energy-saving standards".
Features
The SMB206A and SMB210A integrate single or dual step-down DC-DC buck regulators with on-board MOSFET(s) supplying up dual 3A+3A (SMB206A), or single 6A (SMB210A) output currents. Input voltage range is +4.5V to +16V and output voltage range is +0.8V to VIN, accurate to 2.5% over load/line/temperature. Output voltage is digitally programmable in ~10mV steps while other custom voltages are supported with external resistors . Switching frequency is programmable to 500kHz or 1MHz with 180o phase interleave for SMB206A. Light load efficiency is supported by automatic pulse-skipping operation. Integrated frequency compensation and feedback resistors minimize BoM count, cost and design effort.
Output enable, sequencing, softstart and output voltage (UV) monitoring are all programmable as well. Output voltage monitoring is coupled to "PowerGood" or "RESET" signals with programmable output assignment and output channels can be enabled via the serial I2C interface or by the ENABLE pins. Nominal output voltages maybe changed once the system is powered up, enabling the latest SoC's to reduce platform power using advanced voltage/clock scaling modes. The SMB206A/SMB210A with ~10mV "fine step" output voltage programming allow for easy voltage margining to support rapid system validation and characterization of these same advanced SoC's.
Tiny 3mm x 3mm QFN packaging and minimal external components yield an ultra-compact (typically <120mm2 for dual) solution size. Programmed configuration is held in the OTP non-volatile memory but may be changed in system by host software via the I2C port. The rated operating temperature range is -40C to +85C.
Package, Price and Availability
The SMB206A/SMB210A are available in a tiny thermally enhanced, RoHS-compliant, lead-free 3mm X 3mm, 20-pad QFN. Available now in production quantities, the SMB206A is priced $1.20 each, while the SMB210A are priced at $1.10 respectively in quantities of 10,000 units.
DESIGN SOFTWARE AND PROGRAMMER FOR PROTOTYPE DEVELOPMENT
To speed user product development, Summit offers customers the SMB206EV and SMB210EV companion evaluation boards and a graphical user interface (GUI) software so designers can quickly see the features and benefits and design a prototype intelligent power supply solution. This is a complete development tool that lets designers easily manipulate the characteristics of their systems. The SMB206EV and SMB210EV design kits includes menu-driven Microsoft Windows (R) GUI software to automate programming tasks and also includes all necessary hardware to interface to the USB port of a laptop or PC.
Once a user completes design and prototyping, the SMB206EV and SMB210EV 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.
