3 Description
The TLV62150x device is an easy-to-use
synchronous step-down DC-DC converter optimized
for applications with high power density. A high
switching frequency of typically 2.5 MHz allows the
use of small inductors and provides fast transient
response as well as high output voltage accuracy by
use of the DCS-Control™ topology.
With their wide operating input voltage range of 4 V
to 17 V, the devices are ideally suited for systems
powered from either a Li-Ion or other batteries as well
as from 12 V intermediate power rails. It supports up
to 1-A continuous output current at output voltages
between 0.9 V and 5 V (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 draw quiescent
current of about 19 μA 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 2 μA.
The devices is packaged in a 16-pin VQFN package
measuring 3 mm × 3 mm (RGT).
