3 Description
The TLV62090 device is a high frequency
synchronous step-down converter optimized for small
solution size, high efficiency and suitable for battery
powered applications. To maximize efficiency, the
converter operates in pulse width modulation (PWM)
mode with a nominal switching frequency of 1.4 MHz
and it automatically enters power save mode
operation at light load currents. When used in
distributed power supplies and point of load
regulation, the device allows voltage tracking to other
voltage rails and tolerates output capacitors ranging
from 10 μF up to 150 μF and beyond. Using the
DCS-Control topology, the device achieves excellent
load transient performance and accurate output
voltage regulation.
The output voltage start-up ramp is controlled by the
softstart pin, which allows operation as either a
standalone power supply or in tracking configurations.
Power sequencing is also possible by configuring the
enable (EN) and power good (PG) pins. In power
save mode, the device operates with typically 20-μA
quiescent current. Power save mode is entered
automatically and seamlessly, maintaining high
efficiency over the entire load current range.
The device is available in a 3 mm x 3 mm 16-pin
VQFN (RGT) package.
