Maxim MAXM17532 and MAXM15462 Himalaya uSLIC DC-DC power modules

Maxim Integrated Products’ family of micro system-level IC (uSLIC) modules are said to help reduce solution size and increase efficiency for designers working on space-constrained applications.

The MAXM17532 and MAXM15462 ultrasmall (2.6 x 3 x 1.5 mm) integrated DC-DC power modules are part of Maxim’s extensive portfolio of Himalaya power solutions for industrial, healthcare, communications and consumer markets. The modules provide users with the benefits of high-quality switching regulators with the size and simplicity of a linear regulator (LDO).

The power modules shrink the solution size of the power supply by 2.25x with an ultrasmall package size. This is achieved by integrating a synchronous wide-input Himalaya buck regulator with built-in FETs, compensation and other functions with an integrated inductor. The combination of these components enables the designer to use the modules in small space-constrained systems while complying with mechanical and EMI standards.

In addition, engineers simplify designs as they no longer need to deal with conventional bulky, power-hungry regulators. Instead, they can integrate the ready-made power module into almost the same space of a tiny LDO. In such a small size, designers can achieve high efficiency and lower noise with increased stability.

The DC-DC buck regulator modules, which operate over a wide input range from 4 to 42 V, support multiple applications across nominal input voltages of 5, 12, 24 and 36 V with good headroom. They operate over a temperature range from -40 to 125°C.
