General Description
The MIC45404 device is an ultra-low profile, synchro-
nous step-down regulator module, featuring a unique
2.0 mm height. The module incorporates a DC-to-DC
regulator, bootstrap capacitor, high-frequency input
capacitor and an inductor in a single package. The
module pinout is optimized to simplify the Printed
Circuit Board (PCB) layout process.
This highly-integrated solution expedites system
design and improves product time to market. The inter-
nal MOSFETs and inductor are optimized to achieve
high efficiency at low output voltage. Due to the fully
optimized design, MIC45404 can deliver up to 5A
current with a wide input voltage range of 4.5V to 19V.
The MIC45404 is available in a 54-lead 6 mm x
10 mm x 2.0 mm QFN package with a junction operat-
ing temperature range from -40C to +125C, which
makes an excellent solution for systems in which PCB
real-estate and height are important limiting factors,
and air flow is restricted.
