Dialog Semiconductor announces that Le Mobile & Information Technology (Beijing) Co., Ltd. recently launched smartphones Le Max and Le 1 Pro with power adapters, including Dialog's iW1780 / + iW626 Qualcomm Quick Charge 2.0 adapter chipset. Le Mobile & amp; was established in 2015. Information Technology (Beijing) Co., Ltd. is a subsidiary of LeTV Group. Le Mobile launched the world's first ecosystem phone brand-Le Superphone, which includes three flagship products: Le 1 Pro, Le Max and Le1. Le Max is a high-end device equipped with a 6.33-inch Quad HD display. The Snapdragon 810 chip (2 GHz, eight-core, 64-bit), 4 GB of LPDDR4 RAM, up to 128 GB of internal storage, and 21 with optically stable and true-tone flash Mega-pixel f / 2.0 camera. Le Max also has an ESS Hi-Fi chip, a one-touch fingerprint reader, an infrared remote control, a 3,500 mAh battery, dual LTE SIM support and a wireless HD display link. Compared to Le Max, the Le 1 Pro is smaller and has a reduced feature set. With LeTV's recent entry into the smartphone space, Dialog's adapter solution enables Le Max and Le 1 Plus to charge at extremely fast speeds for a premium user experience, especially for streaming video and other power-hungry applications important. The company said that Dialog's SmartDefender technology helps launch a safer, more reliable fast-charging adapter, which extends Le Mobile's range of breakthrough phone capabilities. Davin Lee, Dialog's senior vice president and general manager of the power conversion business unit, said: "Dialog is quickly ahead of the fast-charging technology in the smartphone market, and currently has an estimated 70% market share." "We are very pleased to be successfully introduced to smart by LeTV Mobile phones, which helps the company add another innovative feature to its high-performance smartphones. " The iW626 fast charge interface IC is located on the secondary side of the AC / DC charger power supply and is used with Dialog's iW1780 PrimAccurate ™ primary-side digital pulse width modulation (PWM) controller. The iW1780 uses a unique secondary-to-primary digital communication link signal to receive all fast charging commands from the iW626 through a single optocoupler. The iW626 + iW1780 chipset supports Quick Charge 2.0 High Voltage Dedicated Charging Port (HVDCP) Class A (5V, 9V, 12V output) applications, which can provide fast voltage conversion and low no-load power consumption below 100mW. Dialog's SmartDefender Advanced IC technology in iW1780 provides adapter security to protect mobile devices from thermal damage caused by shorts in dirty or damaged charging ports or wear of USB cables and connectors. The iW1780 PWM controller's SmartDefender protection reduces the average power delivered to the short circuit by up to 75% without blocking. The company says this helps prevent excessive heat build-up and damage, resulting in safer, more reliable fast charging-all without adding any components.
