Enables Fast Transient Response Supports Safe Start-Up into Pre-Biased Output –40°C to +125°C Junction Temperature Range Thermal Shutdown Protection Short-Circuit Protection with Hiccup Mode Adjustable Current Limit Available in 52-Pin 8 mm x 8 mm x 3 mm QFN
Package The MIC45116 is a synchronous step-down regulator
module, featuring a unique adaptive ON-time control
architecture. 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 4.75V to 20V without
requiring additional cooling.
The MIC45116-1 uses HyperLight LoadВ® (HLL) which
maintains high efficiency under light load conditions by
transitioning to variable frequency, discontinuousmode operation. The MIC45116-2 uses Hyper Speed …
