RTQ2115A-QA  
Charging Port Controller and Integrated 36V 3A Synchronous  
Buck Converter  
Features  
General Description  
USB Charging Port Controller  
Support D+/D- SDP/CDP/DCP Modes per USB  
BC1.2  
The RTQ2115A combines a charging port controller,  
USB 2.0 high-speed data line (D+/D-) switch and a 3A  
synchronous buck converter.  
Support D+/D- Shorted Mode per Chinese  
Telecommunication Industry Standard YD/T  
1591-2009  
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.  
Support Automatic Selection Mode for D+/D-  
Shorted / Divider 3 / 1.2V Mode  
36V 3A Synchronous Buck Converter  
3V to 36V Input Voltage Range  
3A Continuous Output Current  
CC/CV Mode Control  
Adjustable and Synchronizable Switching  
Frequency : 300kHz to 2.2MHz  
Selectable PSM/PWM at Light Load  
Adjustable Soft-Start  
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.  
Adjustable USB Power Output Voltage between  
5V and 6V with Load Line Compensation  
Optional Spread-Spectrum Frequency  
Modulation for EMI Reduction  
Power Good Indicator  
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.  
Enable Control  
USB 2.0 480Mbps Data Switches  
Support Mode Change Among SDP/CDP/DCP  
Auto  
8kV HBM on DS+/DS-  
Over-Temperature Protection  
Cycle-by-Cycle Over-Current Limit Protection  
Input Under-Voltage Protection  
Adjacent Pin-Short Protection  
AEC-Q100 Grade 1 Qualified  
40°C to 125°C Operating Ambient Temperature  
DS+/DS- OVP  
The RTQ2115A is fully specified over the temperature  
range of T = 40°C to 125°C and available in  
J
Applications  
WET-WQFN-32L 5x5.  
Automotive Car Chargers
