DESCRIPTION  
As a member of the SWIFT™ family of DC/DC  
regulators, the TPS5450 is a high-output-current  
PWM converter that integrates a low-resistance  
high-side N-channel MOSFET. Included on the  
Wide Output Voltage Range: Adjustable Down  
to 1.22 V with 1.5% Initial Accuracy  
Internal Compensation Minimizes External  
Parts Count  
substrate with the listed features are  
a
Fixed 500-kHz Switching Frequency for Small  
Filter Size  
high-performance voltage error amplifier that provides  
tight voltage regulation accuracy under transient  
conditions, an undervoltage-lockout circuit to prevent  
start-up until the input voltage reaches 5.5 V, an  
internally set slow-start circuit to limit inrush currents,  
and a voltage feed-forward circuit to improve the  
transient response. Using the ENA pin, shutdown  
supply current is reduced to 18 μA typically. Other  
features include an active-high enable, overcurrent  
limiting, overvoltage protection, and thermal  
shutdown. To reduce design complexity and external  
component count, the TPS5450 feedback loop is  
internally compensated.
