Introduction
The Texas Instruments LM5160DNTBKEVM evaluation module (EVM) helps designers evaluate the
operation and performance of the LM5160A / LM5160 synchronous buck regulator IC in a synchronous
Buck configuration. It also includes the specification for the board, complete application schematic, bill of
materials (BOM), setup instructions, and typical performance curves.
2
Background
The LM5160DNTBKEVM evaluation board provides a fully functional buck regulator, employing the
constant on-time (COT) operating principle. This evaluation board provides a 5-V output over an input
voltage range of 10 V to 60 V. The circuit delivers load current up to 1.5 A. The application schematic is
setup up to operate from a 24 V nominal bus. The nominal switching frequency is approximately 300 kHz.
The LM5160 device name is used generically throughout this document and represents both the LM5160
and LM5160A unless stated otherwise. The only difference between the two is the ability to connect an
external voltage source to the VCC pin of the LM5160A. The board is designed to demonstrate a small
buck solution size for low power wide VIN applications.

Setup
This section describes the connectors, the test points and the jumper on the EVM as well as how to
properly connect and use the LM5160DNTBKEVM with the LM5160, unless stated otherwise.
3.1
Input/Output Connector Description
J1 – Input is the power input terminal for the converter. The terminal block provides an input VIN (+) and
ground (-) connection to allow the user to attach the EVM to a power supply.
J2 – Output is the regulated output voltage for the converter. The terminal block provides a VOUT (+) and
ground (-) connection to allow the user to attach the EVM to a load.
TP1 – (EN) allows the user to remotely shutdown/startup LM5160 while operating in the buck mode. EN
circuitry is not populated on EVM.
TP2 – (SW) allows the user to connect a scope probe to observe the switch node of the converter.
JP1 – Mode pin allows the user to select between the forced CCM and the DCM operation.
3.2
Operation
For proper operation of the LM5160 Buck converter, the input voltage applied across J1 should be
gradually increased. The load on the output (J2) should not exceed 1.5 A. The inductor L1 utilized in this
board is optimized for small solution size. The saturation current rating (ISAT) of the inductor should be
higher than the LM5160 integrated high side FET peak current-limit threshold of 2.875 A (max.).
The nominal switching frequency can be set using the RON (R3 in the EVM) resistor as shown by
Equation 1:

Figure 3. EVM Bottom Copper View with LM5160A
Figure 4. EVM Top Solder Mask with LM5160A
Figure 1 to Figure 4 show the board layout for the LM5160DNTBKEVM PCB. The WSON-12 package
allows a compact leadless IC package buck regulator solution. The LM5160DNTBKEVM is a simple two
layer board. In this EVM, the necessary feedback ripple voltage ( VFB ) required for stable COT operation
over the entire input voltage range is generated by the inductor current flowing through the resistor, RESR
(R8 as shown in Figure 1). This is the least component, minimum cost ripple configuration. There are
placeholders in the EVM ( R7, C6, and C7) which can be populated as required, for the minimum ripple
injection network. If this external ripple configuration is used, substitute R8 with a 0Ω (0805) resistor.
Calculate these component values based on the formulae mentioned under Type 3 ripple configuration in
the LM5160, LM5160A Datasheet (SNVSA03A). See application note AN-1481 for more details for each
ripple generation method.

Figure 5. Buck EVM Schematic with LM5160
When/If used with LM5160, the placeholder for D1 as in Figure 1, must remain unpopulated under all
cases. When evaluating the LM5160A, the designer needs to use the same standard EVM by replacing
the LM5160 IC (when/if populated) with the LM5160A. No other components on board need to be
replaced or removed. With LM5160A IC, the designer can use other nominal output voltage (VOUT), set
between 9 V and 13 V, to externally drive the VCC for improved efficiency requirement. In that case, the
diode in placeholder D1 can be appropriately populated, to the correct voltage ratings. More detail is given
in Section 6 in the Bill of Materials. For more information about the difference between LM5160A and
LM5160, please refer to the LM5160 Datasheet (SNVSA03A).
