RT8068A  
3A, 1MHz, Synchronous Step-Down Converter  
General Description  
Features  
z High Efficiency : Up to 95%  
The RT8068A is a high efficiency synchronous, step-down  
DC/DC converter. It's input voltage range from 2.7V to 5.5V  
that provides an adjustable regulated output voltage from  
0.6V to VIN while delivering up to 3A of output current.  
The internal synchronous low on resistance power  
switches increase efficiency and eliminate the need for  
an external Schottky diode. The switching frequency is  
fixed internally at 1MHz. The 100% duty cycle provides  
low dropout operation, hence extending battery life in  
portable systems. Current mode operation with internal  
compensation allows the transient response to be  
optimized over a wide range of loads and output capacitors.  
The RT8068A is available in WDFN-10L 3x3 and SOP-8  
(Exposed Pad) packages.  
z Low RDS(ON) Internal Switches : 69mΩ/49mΩ at VIN  
= 5V  
z Fixed Frequency : 1MHz  
z No Schottky Diode Required  
z Internal Compensation  
z 0.6V Reference Allows Low Output Voltage
