The TPS51215A is a single phase, D-CAP2™ synchronous buck controller with 2-bits VID inputs that can select up to four independent output voltage with fixed voltage transition slew rate. Table 1-1 displays detailed input and output information.
The TPS51215A supports all POS-CAP and all ceramic MLCC output capacitor options in applications where remote sense is a requirement.
The TPS51215A provides full protection suite, including the following:
It supports the conversion voltage up to 28 V. The devices are available in a 3.0-mm × 3.0-mm 20 pin QFN package and the die operating temperature is specified from –40°C to 125°C.
| EVM | Input Voltage (VIN) Range | Output Current (IOUT) Range |
|---|---|---|
| TPS51215AEVM | 5 V to 24 V | IDC = 0 A to 16 A, IPeak = 0 A to 30 A |
A summary of the TPS51215AEVM performance specifications is provided in Table 2-1. The TPS51215AEVM is designed and tested for VIN = 5 V to 24 V. The ambient temperature is 25°C for all measurements, unless otherwise noted.
