The module incorporates a DC/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 6A current under a wide input voltage range of 4.5V to 26V, without requiring additional cooling. The MIC45205-1 uses Microchip’s HyperLight Load® (HLL) and the MIC45205-2 uses Microchip’s Hyper Speed Control® architecture that enables ultra-fast load transient response, allowing for a reduction of output capacitance. The MIC45205 offers 1% output accuracy that can be adjusted from 0.8V to 0.85 x VIN with two external resistors. Additional features include thermal shutdown protection, input undervoltage lockout, adjustable current-limit, and short-circuit protection. The MIC45205 allows for safe start-up into a pre-biased output.
