Maxim Integrated Products has announced four new micro-system-level IC (“uSLIC”) modules. The MAXM17552, MAXM15064, MAXM17900 and MAXM17903 step-down DC-DC power modules join Maxim’s extensive portfolio of Himalaya power solutions, providing the widest input voltage range (4 V to 60 V) with the smallest solution sizes.
While miniaturization remains the trend for an array of system designs, many of these designs also require a wide range of input voltages. For example, supply voltages in factory automation equipment are susceptible to large fluctuations due to long transmission lines. USB-C and broad 12 V nominal applications require up to 24 V of working voltage protection against transients due to hot plugging of supplies and/or batteries.
The newest Himalaya uSLIC power modules extend the portfolio’s range up to 60 V versus the previous maximum of 42V and come in a solution size (2.6 mm x 3.0 mm x 1.5 mm) less than half the size of the closest competitive offering. The modules feature a synchronous wide-input Himalaya buck regulator with built-in FETs, compensation and other functions with an integrated shielded inductor. Having the inductor in the module simplifies the toughest aspect of power supply design, enabling designers to create a robust, reliable power supply in less than a day.
The newest uSLIC modules are:
• MAXM17552, a 4 to 60V, 100mA module with 100 to 900kHz adjustable switching frequency, 82% efficiency (24V VIN at 5V/0.1A) and external clock synchronization in a 2.6mm x 3mm x 1.5mm package
• MAXM15064, a 4.5 to 60V, 300mA module with 500kHz fixed frequency, 82% efficiency (24V VIN at 5V/0.1A) and built-in output voltage monitoring in a 2.6mm x 3mm x 1.5mm package
• MAXM17900, a 4 to 24V, 100mA module with 100 to 900kHz adjustable switching frequency, 86% efficiency (12V VIN at 5V/100mA), external clock synchronization and built-in output voltage monitoring in a 2.6mm x 3mm x 1.5mm package
• MAXM17903, a 4.5 to 24V, 300mA module with 500kHz fixed switching frequency, 77% efficiency (12V VIN at 3.3V/300mA) and built-in output voltage monitoring in a 2.6mm x 3mm x 1.5mm package
The uSLIC modules can be purchased for the following prices: MAXM17552 for $2.53, MAXM15064 for $2.78, MAXM17900 for $1.39, and MAXM17903 for $1.48 (1000-up, FOB USA); they are also available from authorized distributors. The MAXM17552EVKIT#, MAXM15064EVKIT#, MAXM17900EVKIT# and MAXM17903EVKIT# evaluation kits are available at $29.73 each.
