LTC3608  
18V, 8A Monolithic  
Synchronous Step-Down  
DC/DC Converter  
Description  
Features  
TheLTC®3608isahighefficiency,monolithicsynchronous  
step-downDC/DCconverterthatcandeliverupto8Aoutput  
current from a 4V to 18V (20V maximum) input supply. It  
uses a valley current control architecture to deliver very  
low duty cycle operation at high frequency with excellent  
transient response. The operating frequency is selected  
by an external resistor and is compensated for variations

Power Good Output Voltage Monitor  
Adjustable On-Time/Switching Frequency  
Adjustable Current Limit  
The LTC3608 can be configured for discontinuous or  
forced continuous operation at light load. Forced continu-  
ous operation reduces noise and RF interference while  
discontinuous mode provides high efficiency by reducing  
switching losses at light loads.  
Programmable Soft-Start  
Output Overvoltage Protection  
Optional Short-Circuit Shutdown Timer  
Fault protection is provided by internal foldback current  
limiting,anoutputovervoltagecomparatorandanoptional  
short-circuit shutdown timer. Soft-start capability for sup-  
ply sequencing is accomplished using an external timing  
capacitor.Theregulatorcurrentlimitisuserprogrammable.  
A power good output voltage monitor indicates when  
the output is in regulation. The LTC3608 is available in a  
compact 7mm × 8mm QFN package.
