3 Description

The TLV62130 devices are easy-to-use synchronous

step-down DC-DC converters 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 DCSControl

™ topology.

With their wide operating input voltage range of 3 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 3-A continuous output current at output voltages

from 0.9 V to 5.5 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 device is packaged in a 16-pin VQFN package

measuring 3 mm × 3 mm (RGT).
