DESCRIPTION

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

regulators, the TPS5410 is a high-output-current

PWM converter that integrates a low resistance high

side N-channel MOSFET. Included on the substrate

with the listed features is a 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 TPS5410 feedback loop is internally

compensated.

The TPS5410 device is available in an easy to use

8-pin SOIC package. TI provides evaluation modules

and software tools to aid in quickly achieving high-performance power supply designs to meet

aggressive equipment development cycles.
