Buck (Step-Down) IC

Power Management Voltage Regulator DC to DC Buck External Switching Regulators

MaxLinear, Inc.

MaxLinear’s family of DC to DC switching controllers are the basic element used to build high efficiency and high power point of loads. Driving one or two external FETs in respectively its synchronous or non-synchronous versions, step-down controllers allow the maximum flexibility and tailoring for high performance conversions.

Product Description

Features of MaxLinear’s DC to DC switching controller family include up to 95% efficiency, programmable soft start, undervoltage lockout and overtemperature and short circuit protection. MaxLinear's power solutions are trusted everyday to provide an unprecedented combination of high efficiency, high performance, board space optimization and improved system reliability while reducing costs and time to market.
