PMIC targets ARM-based processors, extends battery life
The WM8320 integrated power management solution maximizes processor performance and extends battery life in portable multimedia devices. It targets applications that use ARM-based processors, particularly netbooks, mobile Internet devices, smartphones, handsets, and digital photo frames.
The device has four dc/dc synchronous regulators, including two 1.2-A regulators that incorporate the company’s BuckWise technology, and two 1.0-A regulators. The 1.0-A regulators can be grouped together to generate a combined 1.6-A output to support large memory banks, or to increase efficiency by pre-regulating any of the 10 integrated LDOs.
The regulator technology helps the PMIC to cope with shifts in power requirements as different product functions are switched on and off by the user. It can also be used in applications where there is no system battery, such as set-top boxes. System designers can choose to reduce processor power consumption by up to 25% over previous generations of regulators, or to increase processor speed by up to 25%. ($3.72 ea/10,000 — available now.)
