DESCRIPTION

•
D-CAP2™ Mode Enables Fast Transient  
Response  
The TPS54328 is an adaptive on-time D-CAP2™  
mode synchronous buck converter. The TPS54328  
enables system designers to complete the suite of  
various end-equipment power bus regulators with a  
cost effective, low component count, low standby  
current solution. The main control loop for the  
TPS54328 uses the D-CAP2™ mode control that  
provides a fast transient response with no external  
compensation components. The adaptive on-time  
control supports seamless transition between PWM  
mode at higher load conditions and Eco-mode™  
operation at light loads. Eco-mode™ allows the  
TPS54328 to maintain high efficiency during lighter  
load conditions. The TPS54328 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 VIN input. The output voltage can be  
programmed between 0.76 V and 7.0 V. The device  
also features an adjustable soft start time. The  
TPS54328 is available in the 8-pin DDA package,  
and designed to operate from –40°C to 85°C.
