Description

  • TPS54239EVM-056, Evaluation Board using TPS54239 single, adaptive on-time, D-CAP2-mode, synchronous buck converter requiring a low external component count. 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 600 kHz. The high-side and low-side switching MOSFETs are incorporated inside the TPS54239 package along with the gate-drive circuitry
