TPS2306 EVM Kit Operating Specifications
Component selection for the TPS2306 EVM was done to configure the circuit for the input and load conditions
shown in Table 4. Therefore, these parameters describe the intended operating conditions of the module.
Current limit and fault timeout options were determined using the nominal load currents shown. In addition, the
load electronics were assumed to have the minimum Under Voltage Lockout (UVLO) thresholds shown. Instead
of UVLO protection, another applicable implementation would be one in which the load electronics are held in
reset for at least the period of the supply voltage ramps.

1. All voltages are with respect to the PCB GND node.
2. Currents are positive into and negative out of the specified terminal.
3. Channel 1 load current is limited by installed value and rating of resistor R1.
The TPS2306 EVM was designed with a high degree of user-programmability, as described in Section 4
(Reconfiguring the EVM). This includes modifications for different input voltage and load current conditions.
However, under no circumstances should the EVM be operated beyond the input supply or load current levels
specified in Table 5.
