connect to the power stage input voltage. Take off the jumper for a user-defined
voltage.
Operation mode selection pin for the device in light-load condition. When this pin is
connected to ground, the device works in PWM mode. When this pin left floating, the
device works in PFM mode.
EN pin. Place a jumper across EN and pin1 to turn on the IC, place a jumper across
EN and pin 3 to turn off the IC.
Modifications
This EVM board is designed to provide access to the feature of the TPS61088. Some modifications can
be made to this EVM board.
2.2.1
Output Voltage
The output voltage of this part is set by the resistor divider network of R2 and R3. To change the output
voltage of the EVM, it is necessary to change the value of the resistors. The value of R2 for a specific
output voltage and specific resistor R3 can be calculated by following equation:

2.2.2
Peak Current Limit Setting
The peak switch current limit is set by the external resistor R5. Ensure that the current limit is higher than
the required peak switch current at the lowest input voltage and highest output power condition. The
current limit value under PFM mode can be calculated by the following equation:
1190000
I LIM =
R5
(2)
Where:
• R5 is the resistance connected between the ILIM pin and ground
• ILIM is the peak switch current limit
Considering the device variation and the tolerance over temperature, the minimum current limit at the
worst case can be 1.3 A lower than the value calculated by Equation 2. So the calculated value ILIM minus
1.3 A should be higher than the peak switch current. When VIN = 3.3 V, to ensure the converter can output
maximum power (VO = 9 V, IO = 3 A) under the PFM mode, we choose R5 = 100 kΩ and ILIM = 11.9 A.
If the converter works in the PWM mode (MODE pin short to ground), the current limit value is 1.6 A lower
than that of the PFM mode. We need to change R5 to 86.6 kΩ to ensure the maximum output power (VO =
9 V, IO = 3 A) under VIN = 3.3 V condition.

Load Transient
The load transient waveform is shown in Figure 2. Please note that the effective output capacitance is only
about 50 µF under VOUT = 9 V DC bias, although four 22-µF ceramic capacitors are used in the EVM.
Larger effective capacitance will help to improve the load transient performance.
