Supports All MLCC Output Capacitor  
DESCRIPTION  
The TPS53310 provides a fully integrated 3-V to 5-V  
VIN integrated synchronous FET converter solution  
with 16 total components, in 200 mm2 of PCB area.  
Due to the low RDS(on) and TI's proprietary  
SmoothPWM™ Skip mode of operation, it enables  
95.5% peak efficiency, and over 90% efficiency at  
loads as light as 100 mA. It requires only two 22-µF  
ceramic output capacitors for a power dense 3-A  
solution.  
SmoothPWM™ Auto-Skip Eco-mode™ for  
Light-Load Efficiency

2.9 V to 3.5 V and conversion voltage from 2.9 V to  
6.0 V, and output voltage is adjustable from 0.6 V to  
0.84 V × VIN.
