Maxim’s family of micro system-level IC ("uSLIC") modules includes the MAXM17532 and MAXM15462 dc/dc converter modules that measure 2.6 mm x 3 mm x 1.5 mm. The uSLIC power modules shrink power-supply size by 2.25x. 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 uSLIC DC-DC buck regulator modules, which operate over a wide input range as low as 4V to as high as 42V, support multiple applications across nominal input voltages of 5V, 12V, 24V, and 36V with reliable headroom for today’s demanding applications. They operate over the -40°C to +125°C temperature range.
The MAXM17532 is available for $2.35 each/1,000 and the MAXM15462 costs $2.53 each/1,000. MAXM15462EVKIT# and MAXM17532EVKIT# evaluation kits are available for $29.73 each. You can read more about Himalaya uSLIC Power Modules and, of course, datasheets are available for the MAXM17532 and MAXM15462.
