AN-1800 Evaluation Kit for LM26480 - Dual DC/DC Buck
Regulators with Dual Low-Noise Linear Regulators
1
LM26480 Overview
The LM26480 is a multi-function, programmable Power Management Unit, optimized for low-power digital
applications. This device integrates two highly efficient 1.5A step-down DC/DC converters and two 300
mA Linear Regulators. The LM26480 is offered in a tiny 4 × 4 × 0.8 mm WQFN 24-pin package.

Evaluation Kit Overview
The LM26480 Evaluation kit comes preassembled with VOUT Buck1 set to 1.8V, VOUT Buck2 set to
3.3V, VOUT LDO1 set to 1.0V, and VOUT LDO2 set to 1.2V. These may not be what the user would like
for their evaluation, so it is possible to change any of the regulator outputs by adjusting its feedback
network. Details are in this document.
The LM26480 Evaluation Kit allows the user to effectively utilize all of the functions of the LM26480. The
evaluation kit consists of:
• LM26480 evaluation board
• LM26480 datasheet
• Evaluation Manual (this document)

Evaluation Kit Setup
Please use ESD protection to prevent any unwanted damaging ESD events!
The user of the LM26480 Evaluation Board can leave the regulator outputs as is or can change them at
any time. In order to change them, remove the existing feedback network and reconfigure it using the
optimal resistors and capacitors for a designated output voltage which can be chosen from Table 1 and
Table 2.

Cautionary Notes
Turrets may be placed somewhat close together on the board. Be careful not to short adjacent pins to
each other!

Getting Started
When the LM26480 evaluation board is configured as needed, and has been properly cleaned, supply the
board with power through the GND and AVDD pins. (See Figure 3) .
You should be able to see the regulators supply the desired voltage.

Using the Evaluation Board
6.1
Enabling the LM26480 Board
The LM26480 evaluation board allows the user to enable the regulators through a jumper, or by applying a
voltage to the regulator’s enable pin.
JP4 and JP5 mark the jumpers for enabling Buck1 and Buck2, respectively. When jumpers are in the
lower position, it shorts the enable pin to GND. Inversely, when the jumpers are in the upper position, the
enable pin is shorted to VDD.
JP7 and JP8 mark the jumpers for enabling LDO2 and LDO1, respectively. When jumpers are in the lower
position, it shorts the enable pin to GND. Inversely, when the jumpers are in the upper position, the enable
pin is shorted to VDD.
If enabling the regulators by applying a voltage to the turret, make sure to remove the jumper for that
specific regulator.

Component Selection for SW1 and SW2
Table 1 shows ideal resistor values to establish buck voltages from 0.8V to 3.5V along with common
resistor values to establish these voltages. Common resistors do not always produce the target value;
error is given in the delta column. In addition to the resistor feedback, capacitor feedback C1 is always
required, and depending on the output voltage capacitor, C2 is also required. See Figure 5.
The output voltages of the bucks of the LM26480 are established by the feedback resistor dividers R1 and
R2 shown on Figure 5.
The equation for determining VOUT is:
VOUT = VFB × (R1 + R2)/R2 where VFB is the voltage on the Buck FBx pin.
The buck control loop will force VFB to be 0.50V ± 3%.
NOTE: Accuracy depends on device process corners, external components tolerance and matching,
and temperature.

LM26480 Hardware Block Description
The LM26480 evaluation board is designed to allow the user to test the blocks independently as well as in
the system. Jumpers 1-6 as described in the Jumper table allow the VDD and GND path of each of the
blocks to be separated from the rest of the blocks.
To look at each of the blocks, follow the instructions below:
1. Start with all the jumpers connected.
2. Remove the connecting jumpers (JP3, JP6, JP9, or JP10) based on the jumper table to isolate the
power and ground planes of the block under test.
3. Connect a power supply (VOUT + 0.3V) to the input of the desired block referenced to its corresponding
ground.
4. Enable the block and proceed with normal testing.
The output voltage of the low dropout regulators can be accessed at the ‘Turrets’ (LDO1 and LDO2)
referenced to GND_M. These are marked on the silkscreen of the evaluation board.
The output voltage of the two buck regulators can be accessed at the ‘Turrets’ BUCK1, BUCK2 referenced
to GND1, and GND2.
External power supplies can be attached to AVDD referenced to GND_C. The voltage supplied to the
system must be between the range of 2.8V to 5.5V.
Table 3. Jumper Settings

Purpose
Note
JP 1,3,6,9,10
These jumpers connect different VINs to the
system VDD (AVDD):
JP1 connects VINLDO1 to AVDD
JP3 connects VIN1 to AVDD
JP6 connects the VIN2 to AVDD
JP9 connects VINLDO1 to AVDDM
JP10 connects VINLDO2 to AVDD
JP3 and JP6 allow the bucks to be powered from the system
power.
JP9 and JP10 allow the LDOs to be powered from the system
power.
JP1 powers the internal bias and error amplifiers from the
system power. The voltage applied to AVDD and VINLDO12
should be in the range of 2.8 – 5.5V.
JP 4,5,7,8
These jumpers tie the enables of each
regulator to VDD:
JP4 - Buck1
JP5 - Buck2
JP7- LDO2
JP8 - LDO1
When connected, these jumpers enable the regulators. If
disconnected, the regulator will power off.
JP 2
This jumper connects the SYNC pin to GND.
SYNC is default OFF. Please contact the Texas Instruments
Sales Office if you wish to use this feature.

PCB Layout Considerations

PCB Layout Considerations
The evaluation board layers from top to bottom are:
1. Top, component side
2. Ground plane
3. Mid signal section
4. Bottom, solder side
For good performance of the circuit, it is essential to place the input and output capacitors very close to
the circuit and use wide routing for the traces allowing high currents.
Sensitive components should be placed far from those components with high pulsating current.
Decoupling capacitors should be close to circuit’s VIN pins. Digital and analog ground should be routed
separately and connected together in a star connection.
It’s good practice to minimize high current and switching current paths.
9.1
Low Drop Out Regulators
Place the filter capacitors very close to the input and output pins. Use large trace width for high current
carrying traces and the returns to ground.
9.2
Buck Regulators
Place the supply bypass, filter capacitor, and inductor close together and keep the traces short. The traces
between these components carry relatively high switching current and act as antennas. Following these
rules reduces radiated noise.
Arrange the components so that the switching current loops curl in the same direction.
Connect the buck ground and the ground of the capacitors together using generous component-side
copper fill as a pseudo-ground plane. Then connect this back to the general board system ground plane at
a single point. Place the pseudo-ground plane below these components and then have it tied to system
ground of the output capacitor outside of the current loops. This prevents the switched current from
injecting noise into the system ground. These components along with the inductor and output should be
placed on the same side of the circuit board, and their connections should be made on the same layer.

Route noise sensitive traces such as the voltage feedback path away from the inductor. This is done by
routing it on the bottom layer or by adding a grounded copper area between switching node and feedback
path. To reduce noisy traces between the power components, keep any digital lines away from this
section. Keep the Feedback node as small as possible so that the ground pin and ground traces will shield
it from the SW or buck output.
Use wide traces between the power components and for power connections to the DC-DC converter
circuit to reduce voltage errors caused by resistive losses.
For the sense lines, make sure to use a Kelvin contact connection.
