DESCRIPTION
The TLV62150 is an easy to use synchronous step
down DC-DC converter optimized for applications
with high power density. A high switching frequency
of typically 2.5MHz allows the use of small inductors
and provides fast transient response as well as high
output voltage accuracy by utilization of the DCS-
Control™ topology.
With its wide operating input voltage range of 4V to
17V, the devices are ideally suited for systems
powered from either a Li-Ion or other batteries as well
as from 12V intermediate power rails. It supports up
to 1A continuous output current at output voltages
between 0.9V and 5V (with 100% duty cycle mode).
The output voltage startup ramp is controlled by the
soft-start pin, which allows operation as either a
standalone power supply or in tracking configurations.
Power sequencing is also possible by configuring the
Enable and open-drain Power Good pins.
In Power Save Mode, the devices show quiescent
current of about 19μA from VIN. Power Save Mode,
entered automatically and seamlessly if load is small,
maintains high efficiency over the entire load range.
In Shutdown Mode, the device is turned off and
shutdown current consumption is less than 2μA.
The devices is packaged in a 16-pin QFN package
measuring 3 × 3 mm (RGT).
