The D-CAP2 control circuit is optimized for low-ESR output capacitors such as POSCAP, SP-CAP, or ceramic types and features fast transient response with no external compensation. The switching frequency is internally set at a nominal 650 kHz. Forced CCM operation maintains constant frequency at light load conditions. The high-side and low-side switching MOSFETs are incorporated inside the TPS563209 package along with the gate-drive circuitry. The low drain-to-source on resistance of the MOSFETs allows the TPS563209 to achieve high efficiencies and helps keep the junction temperature low at high output currents. The TPS563209 dc/dc synchronous converter is designed to provide up to a 3-A output from an input voltage source of 4.5 V to 17 V. The output voltage range is from 0.8 V to 6.5 V. Rated input voltage and output current ranges for the evaluation module are given in Table 1-1. The TPS563209EVM-652 evaluation module (EVM) is a single, synchronous buck converter providing 1.05 V at 3 A from 4.5-V to 17-V input. This user’s guide describes the TPS563209EVM-652 performance.

Some modifications can be made to this module. 3.1 Output Voltage Setpoint To change the output voltage of the EVMs, it is necessary to change the value of resistor R1. Changing the value of R1 can change the output voltage above 0.765 V. The value of R1 for a specific output voltage can be calculated using Equation 1. R1 = R2 ´ (VOUT - 0.765 V ) (1) 0.765 V Table 3-1 lists the R5 values for some common output voltages. Note that the values given in Table 3-1 are standard values and not the exact value calculated using Table 3-1. Table 3-1.

The section also includes test results typical for the evaluation modules and efficiency, output load regulation, output line regulation, load transient response, output voltage ripple, input voltage ripple, start-up, and switching frequency. 4.1 Input/Output Connections The TPS563209EVM-652 is provided with input/output connectors and test points as shown in Table 4-1. A power supply capable of supplying 3 A must be connected to J1 through a pair of 20-AWG wires. The load must be connected to J2 through a pair of 20-AWG wires. The maximum load current capability is 3 A. Wire lengths must be minimized to reduce losses in the wires. Test point TP1 provides a place to monitor the VIN input voltages with TP2 providing a convenient ground reference. TP7 is used to monitor the output voltage with TP8 as the ground reference.
