MIC45404 is an ultralow profile synchronous step-down regulator module, featuring a unique 2.0 mm maximum 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 PCB layout process.
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 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-pin 6mm × 10mm × 2.0mm max QFN package with a junction operating temperature range from –40 ºC to +125 ºC, which makes an excellent solution for systems in which PCB real-estate and height are important limiting factors and air flow is restricted.

| The MIC45404 Evaluation board is intended to facilitate the evaluation of the MIC4504 power module under various settings and operating conditions. The basic parameters are a Vin supply of 4.5V to 19V, an output voltage of 0.7V up to 3.3V at 5A. Due to optimized pinout, the evaluation board can achieve a 2-layer only routing (top and bottom), while internal planes are connected to GND and kept as solid as possible for better thermal performance.

| Buck 2 click is a powerful step down DC-DC switching regulator. It gives a high precision regulated voltage at its output and it can handle an ample amount of current. Buck 2 click is highly configurable - the output voltage, maximum current limiting, and the switching frequency parameters can be controlled via the IC pins routed to the mikroBUS™ socket, providing a simple and secure connection to the host MCU.
The input voltage can range from 4.5V to 19V and the output can be set to work in several discrete steps, ranging from 0.7V to 3.3V. Features, such as the wide range of input voltages, pin configurable working parameters, internal soft start, thermal shutdown, hiccup mode short-circuit protection and high switching efficiency, make this device a perfect choice for any step-down application which demands reasonably high current and accurate voltage regulation with clean and ripple-free low voltage power supply - such as the embedded electronic devices, servers, routers, data storage devices, low power ICs and similar. |
