AC-DC converter, protocol controller, USB PD Phy, direct charger integration, Type C solution implementation

NXP Semiconductors has announced a fast-charging USB Type C solution. This end-to-end solution is compact yet features high efficiency and unique fast-charging capabilities, along with USB PD PHY specifications, and complies with the Type C Port Controller (TCPC) standard.

The new products include a Type C port controller, a 6A direct charger, a direct charging interface, and a USB-PD controller. By employing a USB Type C connector, this solution enables simultaneous data transfer, video transmission, and power charging, while providing full-scale power-on-demand and fast charging capabilities for mobile phones. Supporting both mobile and computing devices, this functionality is implemented as a single unit. It reduces heat generation by providing precise voltage and current regulation loops to protect the battery and system, allowing consumers to charge their smartphones faster via the direct charger. NXP stated that, to expand compatibility, the solution was designed to be the first to supply USB power through a USB-IF standard body.

The PTN5110 Type C port controller is a USB-IF TCPC PHY with a low power capability of 30uA in active sync mode, supporting standard programmable USB power supply while reducing the package size by 57% compared to the first generation. TCPC PHY can reduce overall system BOM costs by simplifying the system architecture through the reduction of redundant MCUs.

The PCA9491UK 6A direct charger reduces heat generated by mobile devices through a low-on resistance switch (13 mohm) and supports programmable options to meet specific customer needs. Designed as the smallest 42-pin WLCSP, it supports a wide range of voltage and power regulation loops, enabling accurate temperature measurement for dies, VBUS, batteries, and 30V support technologies.

The TEA 1901 SCP Direct Charge Interface Controller and the TEA 1905x USB-PD Fast Charge Interface Controller are among the products that integrate USB PD 3.0 and Fast Charge 2.0 and 3.0. Designed for use with the TEA 1936x and TEA 199x, these products enhance the power efficiency of chargers for small mobile phones. They adopt the industry's latest interface protocols. The controllers consist of various state-of-the-art fast charging protocols, implementing a wide range of voltage and current regulation loops to protect the system and battery.

"This latest solution is a multi-protocol standard USB Type C power and high-speed switching device that enables seamless connectivity and simultaneous charging via a single cable regardless of orientation," said Chae Lee, Senior Vice President and General Manager of Security Interfaces and Power at NXP. "USB Type C is the fastest-growing solution in the mobile market, and the USB Type C solutions provided by NXP offer both easy integration and high efficiency."
