The TPS62184 is a 6-A, dual-phase, synchronous, step-down converter in a 2 × 3-mm, WCSP package.
Table 1-1 provides a summary of the TPS62184EVM-581 performance specifications. All specifications are given for an ambient temperature of 25°C.
Specification | Test Conditions | Min | Typ | Max | Unit |
---|---|---|---|---|---|
Input voltage | 4 | 17 | V | ||
Output voltage setpoint | 1.8 | V | |||
Output current | VOUT ≤ 1.8 V | 0 | 6 | A | |
VOUT > 1.8 V and ≤ 2.5 V | 0 | 5.5 | A | ||
VOUT > 2.5 V and ≤ 3.5 V | 0 | 5 | A | ||
Soft-start time | Ramp time of VOUT | 825 | µs |
The output voltage of the EVM may be adjusted within the range stated in the device data sheet. Additional input and output capacitors can also be added. A lower profile inductor may also be used to reduce the total solution height. Finally, the input voltage at which the IC turns on can be adjusted with two resistors.
The output voltage may be adjusted by changing the values of R1 and R2. Be sure and keep the output voltage within the range specified in the device data sheet. Setting an output voltage above 1.8 V reduces the maximum amount of current which can reliably be delivered, per Table 1-1. See the data sheet for details.
