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.
