Device Functional Modes (continued)

9.4.2 Thermal Shutdown

The device enters thermal shutdown once the junction temperature exceeds typically TJSD. Once the device

temperature falls below the threshold with hysteresis, the device returns to normal operation automatically.

Power Good is pulled low when thermal protection is triggered.

10 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

10.1 Application Information

The TLV6256x devices are synchronous step-down converters optimized for small solution size and high

efficiency. The devices integrate switches capable of delivering an output current up to 1.5 A.

10.2 Typical Application

TLV62565 2.7-V to 5.5-V input, 1.2-V output converter.

10.2.1 Design Requirements

10.2.1.1 Output Filter Design

The inductor and output capacitor together provide a low-pass frequency filter. To simplify this process, Table 2

outlines possible inductor and capacitor value combinations.
