RTQ2816  
6A, 18V, Synchronous Step-Down Converter  
General Description  
Features  
Low RDS(ON) Power MOSFET Switches 26mΩ/19mΩ  
Input Voltage Range : 4.5V to 18V  
Adjustable Switching Frequency : 200kHz to 1.6MHz  
Current-Mode Control  
The RTQ2816 is a high efficiency, monolithic synchronous  
step-downDC-DC converter that can deliver up to 6Aoutput  
current from a 4.5V to 18V input supply. The RTQ2816  
current-mode architecture with external compensation  
allows the transient response to be optimized over a wide  
range of loads and output capacitors. Cycle-by-cycle  
current limit provides protection against shorted outputs  
and soft-start eliminates input current surge during start-  
up. Fault condition protections include output under-voltage  
protection, output over-voltage protection, and over-  
temperature protection. The low current shutdown mode  
provides output disconnection, enabling easy power  
management in battery-powered systems.  
Synchronous to External Clock : 200kHz to 1.6MHz  
Accurate Voltage Reference 0.8V 1%, Over −40°C  
to 85°C  
Monotonic Start-Up into Pre-biased Outputs  
Adjustable Soft-Start  
Power Good Indicator  
Under-Voltage and Over-Voltage Protection  
Input Under-Voltage Lockout  
RoHS Compliant and Halogen Free  
Ordering Information  
Applications
