Introduction

AI Translation

The RTQ2115A combines a charging port controller, USB 2.0 high-speed data line (D+/D-) switch and a 3A synchronous buck converter. The RTQ2115A provides the electrical signatures on D+/D- to support charging schemes compatible with the USB 2.0 Battery Charging Specification BC1.2 and Chinese Telecommunication Industry Standard YD/T 1591-2009. Auto-detect mode is also integrated which supports USB 2.0 Battery Charging Specification BC1.2 Dedicated Charging Port (DCP), Divider 3 mode and 1.2V shorted mode to comply with the legacy fast charging mode of mobile devices. The RTQ2115A integrates a high efficiency, monolithic synchronous buck converter that can deliver up to 3A output current from a 3V to 36V wide range input supply and is protected from load-dump transients up to 42V. The RTQ2115A has constant current control to achieve adjustable USB current limit and implement the current sense signal for adjustable USB power output voltage with load line compensation. The converter includes optional spread-spectrum frequency modulation to overcome EMI issue and complete protection for safe and smooth operation in all applied conditions. Protection features include cycle-by-cycle current limit for protection against shorted outputs, soft-start control to eliminate input current surge during start-up, input under-voltage lockout, output under-voltage protection, output over-voltage protection and over-temperature protection. The RTQ2115A can be used to support Type-A connector. The RTQ2115A is fully specified over the temperature range of TJ = -40℃ to 125℃ and available in WET-WQFN-32L 5x5.
