1 Introduction

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:

  • OVP
  • UVP
  • OCL
  • V5IN UVLO
  • OTP

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.
