MIC45212

In Production

MIC45212 is a synchronous step-down regulator module, featuring a unique adaptive ON-time control architecture. The module incorporates a DC-to-DC controller, power MOSFETs, bootstrap diode, bootstrap capacitor, and an inductor in a single package; simplifying the design and layout process for the end user. This highly-integrated solution expedites system design and improves product time-to-market. The internal MOSFETs and inductor are optimized to achieve high efficiency at a low output voltage. The fully-optimized design can deliver up to 14A current under a wide input voltage range of 4.5V to 26V, without requiring additional cooling. The MIC45212-1 uses HyperLight Load® (HLL) while the MIC45212-2 uses Hyper Speed Control™ architecture, which enables ultra-fast load transient response, allowing for a reduction of output capacitance. The MIC45212 offers 1% output accuracy that can be adjusted from 0.8V to 85% of VIN with two external resistors. Additional features include thermal shutdown protection, input undervoltage lockout, adjustable current limit, and short circuit protection. The MIC45212 allows for safe start-up into a pre-biased output.

    • MIC45212 Current Sharing Reference Design ( ARD00777 )

      MIC45212

      ​The MIC45212 Current Sharing Ref. Design improves the current capability of the MIC45212 from 14A to 28A while also decreasing the response time and improving load transient response. This is achieved by paralleling two MIC45212 with one working as a master and the other as slave to follow the master's current. Losless sensing is used to maintain high efficiency in heavy load situations while...
