Summitmroelectronics introduces the latest multi-output programmable manager ic member smb119, which is targeted at portable consumer devices and integrates seven precision programmable regulators with extensive digital power control. This "single" solution offers the highest design flexibility while reducing system size and cost.
characteristic
The smb119 incorporates three synchronous bucks, two boost converters, a configurable boost or buck converter and an ldo linear regulator. It also has a fully programmable system monitor that monitors the undervoltage or overvoltage path used. The user can choose how smb works under abnormal conditions (reset output, power off or forced off), so system reliability is maximized.
The power manager operates at a frequency of 1 mhz, taking into account the system components of space savings. The dc-dc power conversion efficiency is up to 95%, reducing heat dissipation and improving the life of portable systems. The power-down mode reduces current consumption to 0.1μa, while automatic pwm/pfm operation increases light load efficiency, further enhancing battery life. The pwm mode can also be used for sensitive rf or applications, as well as built-in short-circuit current limiting and thermal protection for enhanced reliability.
application
The smb119 is ideal for a wide range of portable consumer applications such as digital cameras/portable cameras (dsc/dcc), portable media players (mp3/mpeg4), and next-generation smart. Dynamic voltage management features are especially useful in xsale and armcpu applications that require LED brightness control. Smb119 can be input directly from +2.7v-+6.0v, suitable for single power supply applications, but also for line power applications. The device's operating temperature range is +0°C-+70°C or -40°C-+85°C, and the package is 7mm x 7mm 48-pin qfn, lead-free and meets rohs.
Price and availability
The smb119 is now in volume production, with a unit price of $3.74 for 10,000-piece quantities.
