MAX16425AGCJ+

MAX16425A is a fully-integrated, highly efficient step-down switching regulators for applications operating from 4.5V to 16V input supplies that require up to 25A maximum load. This single-chip regulator provides a compact high-efficiency, power-delivery solution for precision outputs that demand fast transient response. The programmable features include internal/external reference voltage, output voltage set-point, switching frequency, overcurrent protection level, and soft-start timing. Discontinuous current mode (DCM) operation can be enabled through pin-strapping to improve light-load efficiency. This includes multiple protection and measurement features. Positive and negative cycle by-cycle OCP, short-circuit protection and overtemperature protection (OTP) ensure robust design. Application includes servers/μServers, I/O and chipset supplies, GPU core supply, DDR memory VDDQ, VPP and VTT, point-of-load (PoL) applications.
