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 the HyperLight Load (HLL) while the MIC45212-2 uses the Hyper Speed Control (HSC) 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 0.
85*VIN with two external resistors.
Additional features include thermal shutdown protection, input undervoltage lockout, adjustable cu...
