General Description
MIC45205 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 4.5V 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.
