MIC45116数据手册集成电路（IC）的DCDC开关稳压器规格书PDF

描述 Description

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 Load® (HLL) which maintains high efficiency under light load conditions by transitioning to variable frequency, discontinuous-mode operation. The MIC45116-2 uses Hyper Speed Control® architecture which enables ultra-fast load transient response, allowing for a reduction of output capacitance. The MIC45116 offers 1% output accuracy that can be adjusted from 0.8V to 85% of the input (PVIN) with two external resistors. Additional features include thermal-shutdown protection, adjustable current limit, and short-circuit protection. The MIC45116 allows for safe start-up into a pre-biased output.
