DIALOG launched Pump Express protocol compatible fast charging AC / DC Controller

Highly integrated power management, audio , AC / DC, solid state lighting and short-range wireless technology provider Dialog Semiconductor Ltd. announced the world's first compatible MediaTek latest Pump Express ™ fast charging protocol AC / DC fast charge controller . This single-chip solution iW1680 use Dialog intelligent fast charging algorithm and digital primary-side digital control technology , significantly reduces the charging USB AC / DC wall charger long , and its materials (BOM) cost is not higher than the slower traditional charging technology . Pump Express is a proprietary protocol MediaTek aims to feature phones , smart phones and tablet computers and other mobile devices Quick charge with a maximum charge of 45% faster than conventional chargers.
Traditional USB AC charger is rated at 5 volts , you need the handheld device buck converter voltage down to the desired output voltage . Dialog 's built-in intelligence to use fast charging digital algorithm , iW1680 be compatible with MediaTek Pump Express protocol to communicate with the phone , and then the flexible adjustment of the output voltage wall charger , ready to provide the best mobile phone level . This not only makes the phone without a built- input buck converter and reduce total system cost , but also a more efficient delivery of power to the cell phone battery and shorten the charging time.
Dialog With the latest version PrimAccurate ™ derived primary side controller platform , has been a leader in the AC / DC power supply accurate primary-side control. With this lead , iW1680 fast charging AC / DC controller used in the digital analysis capabilities within the primary side of isolated power charger , so no secondary side with any smart voltage regulation function can also be achieved , further reducing costs.
Dialog Semiconductor Limited Power Conversion Mark Tyndall GM senior vice president of strategic development and corporate business group , said: "Today, the sharp increase in power consumption applications are rapidly emerging, shorten the charging time is one of the development trend of the most interesting smartphones for close cooperation with MediaTek , we are excited , launched the world's first hand Pump Express protocol compatible AC / DC controller , on the other hand will be able to quickly and effectively get fast charging technology complementary to the Chinese market .
iW1680 support up to 7.5W of power adapters , high and less than 30mW no-load power consumption with high efficiency. Between your phone and iW1680 communicate through a VBUS power cord. By analyzing the VBUS signal and adjusts its output signal , iW1680 the AC / DC adapter to the primary side of the transformer for the digital management of the voltage regulator . iW1680 can easily and effectively control the low-cost bipolar junction transistor (BJT), thereby further reducing BOM cost and electromagnetic interference (EMI).
iW1680 a 6 -pin SOT23 package, comprehensive protection functions include : built-in output short circuit , low output impedance , output overvoltage , output overcurrent and overtemperature protection output .
