RT7296A  
3A, 17V Current Mode Synchronous Step-Down Converter  
General Description  
Features  
The RT7296A is a high-efficiency, 3A 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  
3A Output Current  
Internal N-Channel MOSFETs  
Current Mode Control  
integrates 80mhigh-side and 30mlow-side  
MOSFETs to achieve high efficiency conversion. The  
current mode control architecture supports fast  
transient response and internal compensation. A  
cycle-by-cycle current limit function provides protection  
against shorted output. The RT7296A 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  
RT7296A is available in the TSOT-23-8 (FC) package.  
Fixed Switching Frequency : 500kHz  
Synchronous to External Clock : 200kHz to 2MHz  
Cycle-by-Cycle Current Limit  
TTH Power-Save Mode  
Internal Soft-Start Function  
Input Under-Voltage Lockout  
Output Under-Voltage Protection  
Thermal Shutdown  
Applications  
Industrial and Commercial Low Power Systems  
Computer Peripherals
