RT6296A  
2A, 17V Current Mode Synchronous Step-Down Converter  
General Description  
Features  
The RT6296A is a high-efficiency, 2A current mode  
synchronous step-down DC-DC converter with a wide  
input voltage range from 4.5V to 17V. The device  
4.5V to 17V Input Voltage Range  
2A Output Current  
Internal N-Channel MOSFETs  
Current Mode Control  
integrates 100mhigh-side and 40mlow-side  
MOSFETs to achieve high efficiency conversion. The  
current mode control architecture supports fast  
transient response and internal compensation. The  
RT6296A provides TTH pin to adjust transition point  
from PSM to PWM in order to balance efficiency and  
output ripple. A cycle-by-cycle current limit function  
provides protection against shorted output. The  
RT6296A provides complete protection functions such  
as input under-voltage lockout, output under-voltage  
protection, over-current protection, and thermal  
shutdown. The PWM frequency is adjustable by the  
EN/SYNC pin. The RT6296A is available in the  
TSOT-23-8 (FC) package.  
Fixed Switching Frequency : 500kHz  
Synchronous to External Clock : 200kHz to 2MHz
