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).
