Renesas introduces new power management IC for tablets and netbooks

Oak Trail advanced power management features are claimed to deliver up to a 50% reduction in average

Renesas Electronics, a provider of advanced semiconductor systems, has introduced a single-chip power management IC (PMIC), the uPD9977, to provide greater energy efficiency for Intel Atom processor (Oak Trail) based tablets and netbooks.

With the support of Renesas Electronics' new uPD9977 PMIC, the Oak Trail advanced power management features are claimed to deliver up to a 50% reduction in average power consumption with full HD-video playback.

In addition, the new uPD9977 facilitates voltage regulation optimized to deliver improved performance for high- and light-load efficiency and also offers full documentation, including PMIC schematics and layout references, to enable rapid implementation.

The enhanced PMIC capabilities are expected to enhance the performance of the future Intel Atom processor-based devices, including long battery life, portability and productivity.

Renesas Electronics senior manager of 3rd MCU business division Masahiko Kashimura said that as new solutions like the 'Oak Trail' evolve to meet skyrocketing user demands for always-on connected mobility, advanced energy efficiency and smaller form factors will be key for broad user adoption.

"Renesas Electronics' new Intel-based uPD9977 PMIC is an example of the important role of core silicon technologies in achieving longer battery life for these mobile multimedia devices," Kashimura said.
