DC/DC modules increase voltages for industrial and consumer applications
The MAXM17552, MAXM15064, MAXM17900 and MAXM17903 step-down DC/DC power modules have been added to Maxim’s Himalaya portfolio, providing input voltage ranging from four to 60V and a small form factor.
Supply voltages in factory automation equipment are susceptible to large fluctuations due to long transmission lines. USB-C and broad 12V nominal applications require up to 24V of working voltage protection against transients due to hot plugging of supplies and/or batteries, explains Maxim. The Himalaya uSLIC power modules extend the portfolio’s range up to 60V from 42V and are available in a smaller form factor (2.6 x 3.0 x 1.5mm) which is less than half the size of the closest competitive offering, says Maxim. The modules feature a synchronous wide-input Himalaya buck regulator with built-in FETs, compensation and other functions with an integrated shielded inductor to simplify power supply design.
One of the new uSLIC modules is the MAXM17552, a four to 60V, 100mA module with 100 to 900kHz adjustable switching frequency. It has 82 per cent efficiency (24V VIN at 5V/0.1A) and external clock synchronisation.
The MAXM15064 is a 4.5 to 60V, 300mA module with 500kHz fixed frequency, also with 82 per cent efficiency (24V VIN at 5V/0.1A) and built-in output voltage monitoring.
The MAXM17900 is a four to 24V, 100mA module with 100 to 900kHz adjustable switching frequency, 86 per cent efficiency (12V VIN at 5V/100mA), external clock synchronisation and built-in output voltage monitoring.
Finally, the MAXM17903 is a 4.5 to 24V, 300mA module with 500kHz fixed switching frequency, 77 per cent efficiency (12V VIN at 3.3V/300mA) and built-in output voltage monitoring.
The uSLIC modules comply to CISPR 22 (EN 5022) Class B EMI, eliminating the need for power supply redesigns and are JEDEC certified to withstand drop, shock and vibration.
Maxim also offers evaluation kits for each uSLIC modules.
