General Description

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 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.
