Negative Charge Pumps Achieve

作者： 時(shí)間：2011-04-11 來(lái)源：網(wǎng)絡(luò ) 收藏
. A positive-charge-pump architecture switches from its highest efficiency mode (1x) when any single WLED current falls below a predetermined level. Thus, systems with a large number of WLEDs and large forward-voltage mismatch waste a significant amount of power.

A negative-charge-pump architecture overcomes the inefficiencies typically encountered in positive-charge-pump designs. Devices such as the MAX8647/MAX8648 use this negative-charge-pump architecture, as well as individual mode switching for each LED, to dramatically improve efficiency and extend battery runtime. These WLED drivers enable designers to achieve inductor-like efficiencies while benefiting from the simplicity and cost savings offered by charge-pump solutions.

A similar version of this article appeared in Korean in the May 2008 issue of Semiconductor Network.
