DESCRIPTION  
Highly Efficient Integrated FETs Optimized  
for Lower Duty Cycle Applications  
The TPS54226 is a adaptive on-time D-CAP2™  
mode synchronous buck converter. TheTPS54226  
enables system designers to complete the suite of  
various end equipments power bus regulators with a  
cost effective, low component count, low standby  
current solution. The main control loop for the  
TPS54226 uses the D-CAP2mode control which  
provides a fast transient response with no external  
compensation components. The adoptive on-time  
control supports seamless operation between PWM  
mode at heavy load condition and reduced frequency  
Eco-Modeoperation at light load for high efficiency.  
The TPS54226 also has a proprietary circuit that  
enables the device to adopt to both low equivalent  
series resistance (ESR) output capacitors, such as  
POSCAP or SP-CAP, and ultra-low ESR ceramic  
capacitors. The device operates from 4.5-V to 18-V  
VCC input, and from 2-V to 18-V VIN input power  
supply voltage. The output voltage can be  
programmed between 0.76 V and 5.5 V. The device  
also features an adjustable slow start time and a  
power good function. The TPS54226 is available in  
the 14 pin HTSSOP or 16 pin QFN package, and  
designed to operate from 40°C to 85°C.
