Power Management IC: Adding fuel to the development of mobile terminals

In addition to achieving ultra-long standby, power management technology also has a deeper impact on the development of mobile terminals, and the boundaries between smartphones, tablets, and PCs will continue to blur.

With the continuous diversification of functions of the mobile terminal, the user's use time on the mobile terminal is also getting longer and longer, and the demand for energy consumption is increasing. Super long-term standby has become the current dream of mobile phones, tablet computers and other users. Power management technology will make long standby possible.

The development of power management technology is accelerating. Freescale has introduced several series of power management chips (PMUs) successively, from the earlier MC13892 and MC34708 to the new generation of PF series devices. The seamless connection of the MX 6 application processor ensures high power efficiency while providing software support, which also reduces the power consumption of the product. Currently used in consumer electronics and automotive electronics.

Liu Zhi, Freescale's power application engineer, said that "the power management IC will be an important component of the mobile terminal and will effectively improve the battery life of the device, and this year will grow with the strong growth of handheld devices."

TI also introduced the National LM3242 and LM3243 regulators on its power management ICs to reduce heat dissipation for 2G, 3G and 4G LTE portable devices, reducing battery current consumption by 50% or more, and effectively extending battery life. TI's new LM3242 and LM3243 dynamically adjust the amount of power provided to the PA based on the actual power required, resulting in significant energy savings.

Recently, Dialog Semiconductor, a power management and audio solutions provider, also announced that its single-chip system power management chip was used to optimize Freescale's multi-core i. Power requirements for tablets, infotainment systems, media hubs, and other smart devices of the MX 6 Series application processor. Its power management chip has an effective PCB footprint of less than 200mm2 and a height of 1mm, ensuring the creation of thinner, lighter mobile products with longer battery life.

In addition to achieving ultra-long standby, power management technology also has a deeper impact on the development of mobile terminals. Christophe Chene, vice president of Asian operations at Dialog, told the China Electronics News: “Power management ICs will have higher levels of integration, flexibility and configurability, which will continue to drive the development of smart terminals, making them increasingly thinner and lighter. The life expectancy will be longer and longer and the performance will be higher and higher. Under the impetus of the power management IC, the boundaries between smart phones, tablet PCs and PCs will continue to be blurred and the market will influence each other to converge.”
