Also included are the performance specifications, the schematic, and the bill of materials for the TPS54240EVM-VSON. 1.1 Background The TPS54240 DC/DC converter is designed to provide up to a 2.5-A output from an input voltage source of 3.5 V to 42 V. Rated input voltage and output current range for the evaluation module are given in Table 1. This evaluation module is designed for VSON package. The switching frequency is internally set at a nominal 500 kHz. The high-side MOSFET is incorporated inside the TPS54240 package along with the gate-drive circuitry. The low drain-to-source on-resistance of the MOSFET allows the TPS54240 to achieve high efficiencies and helps keep the junction temperature low at high output currents. The compensation components are external to the integrated circuit (IC), and an external divider allows for an adjustable output voltage. Additionally, the TPS54240 provides adjustable slow start and undervoltage lockout inputs. The absolute maximum input voltage is 42 V for the TPS54240EVM-VSON. Table 1. Input Voltage and Output Current Summary EVM INPUT VOLTAGE RANGE OUTPUT CURRENT RANGE TPS54240EVM-VSON VIN = 7 V to 24 V 0 A to 2.5 A Note that EN has an absolute maximum rating of 5 V input and a 1.25-V typical threshold voltage, the selection of R1 and R4 limits input voltage range between 7 V and 24 V. 1.2 Performance Specification Summary A summary of the TPS54240EVM-VSON performance specifications is provided in Table 2. Specifications are given for an input voltage of VIN = 12 V and an output voltage of 3.3 V, unless otherwise specified. The TPS54240EVM-VSON is designed and tested for VIN = 7 V to 24 V. The ambient temperature is 25°C for all measurements, unless otherwise noted. The EVM may be modified by the user to operate from input voltages up to the 42 V operating limit of the TPS54240.

The EVM offers resistors, capacitors and test points to configure the output voltage, enable (EN) pin, set frequency, and external clock synchronization. The VSON package offers an exposed thermal pad, which must be soldered to the copper landing on the PCB for optimal thermal performance. The PCB consists of a 4-layer design. There are 2-oz copper planes on the top and bottom and 1-oz copper mid-layer planes to dissipate heat with an array of thermal vias under the thermal pad to connect to all four layers. Test points have been provided for ease of use to connect the power supply, required load and to monitor critical signals. The 12-pin edge connector can also be used to facilitate the use of a cable harness if one is required. Figure 17.

Some modifications can be made to this module. 5.1 Output Voltage Setpoint The voltage divider of R3 and R6 is used to set the output voltage of the EVM. The 51-Ω resistor R2 is provided as an aid to check the loop response of the circuit. To change the output voltage of the EVM, it is necessary to change the value of resistor R3. Changing the value of R3 can change the output voltage above 0.8 V or 90% VIN. The value of R3 for a specific output voltage can be calculated using Equation 1. (1) Table 5 lists the R3 values for some common output voltages. Note that VIN must be in a range so that the minimum on-time is greater than 130 ns, and the maximum duty cycle is less than 90%. Higher duty cycles are possible, but may result in uneven switching behavior. The values given in Table 5 are standard values, not the exact value calculated using Equation 1. Table 5. Output Voltages Available OUTPUT VOLTAGE (V) R3 VALUE (kΩ) 1.8 12.4 2.5 21.5 3.3 31.6 5 52.3 Be aware that changing the output voltage can affect the loop response. It may be necessary to modify the compensation components. Also, changing output voltage may need to change LOUT and COUT as well. Check COUT voltage rating if higher VOUT is used. See the device data sheet for details. 5.2 Operating Frequency, Soft Start, and UVLO The operating frequency, soft-start time, and UVLO voltage may also be adjusted. R5 sets the operating frequency, C11 sets the soft-start time and the resistor divider of R1 and R2 sets the UVLO start and stop voltages. See the TPS54240 device data sheet for details on adjusting these parameters.
