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 &F up to 150 &F 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-&A 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 & 3 mm 16-pin VQFN (RGT) package.
