DESCRIPTION

Fixed 500-kHz Switching Frequency for Small

Filter Size

As a member of the SWIFT™ family of DC/DC

regulators, the TPS5450 is a high-output-current

PWM converter that integrates

high-side N-channel MOSFET. Included on the

substrate with the listed features are

•

18-µA Shutdown Supply Current

a low-resistance

Improved Line Regulation and Transient

Response by Input Voltage Feed Forward

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.

•

System Protected by Overcurrent Limiting,

Overvoltage Protection, and Thermal

Shutdown

•

Available in Small Thermally Enhanced 8-Pin

SOIC PowerPAD™ Package

For SWIFT™ Documentation, Application

Reports and Design Software, See the TI

Website at www.ti.com/swift

APPLICATIONS

•

High-Density Point-of-Load Regulators

LCD Displays, Plasma Displays

Battery Chargers

The TPS5450 device is available in a thermally

enhanced, 8-pin SOIC PowerPAD™ package. TI

provides evaluation modules and software tools to aid

in achieving high-performance power supply designs

to meet aggressive equipment development cycles.

12-V/24-V Distributed Power Systems
