The TPS62090-Q1 devices are a family
of high-frequency, synchronous, step-down converters optimized for small design
size, high efficiency, and are designed for battery-powered applications. To
maximize efficiency, the converters operate in pulse width modulation (PWM) mode
with a nominal switching frequency of 2.8MHz to 1.4MHz and automatically enter power
save mode operation at light load currents. When used in distributed power supplies
and point-of-load regulation, the devices allow voltage tracking to other voltage
rails and tolerate output capacitors ranging from 10µF up to 150µF and beyond. Using
the DCS-Control topology, the devices achieve excellent load transient performance
and accurate output voltage regulation.
The output voltage start-up ramp is
controlled by the SS pin, which allows operation as either a standalone power supply
or in tracking configurations. Power sequencing is also possible by configuring the
enable and power good pins. In power save mode, the devices operate at typically
20µA quiescent current. Power save mode is entered automatically and seamlessly
maintaining high efficiency over the entire load current range.
