9 Applications 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, as well as validating and testing their design

implementation to confirm system functionality.

9.1 Application Information

The TLVM13610 synchronous buck module requires only a few external components to convert from a wide

range of supply voltages to a fixed output voltage at an output current up to 8 A. To expedite and streamline the

process of designing of a TLVM13610-based regulator, a comprehensive TLVM13610 quickstart calculator tool is

available by download to assist the system designer with component selection for a given application.

9.2 Typical Applications

For the circuit schematic, bill of materials, PCB layout files, and test results of a TLVM13610-powered

implementation, see the TLVM13610EVM.

9.2.1 Design 1 – High-Efficiency 8-A (10-A peak) Synchronous Buck Regulator for Industrial Applications

The following figure shows the schematic diagram of a 5-V, 8-A buck regulator with a switching frequency of 1

MHz. In this example, the target half-load and full-load efficiencies are 93.4% and 91.5%, respectively, based on

a nominal input voltage of 24 V that ranges from 9 V to 36 V. A resistor RRT of 15.8 kΩ sets the free-running

switching frequency at 1 MHz.

9.2.1.1 Design Requirements

Table 9-1 shows the intended input, output, and performance parameters for this application example. Note that

if the input voltage decreases below approximately 6 V, the regulator operates in dropout with the output voltage

below its 5-V setpoint.
