To address 40-V load
dump-tolerant applications, the ultra-compact, pin-compatible MAX20075 and
MAX20076 step-down converters from Maxim Integrated claim the industry’s lowest
quiescent current in an ultra-small solution with integrated compensation, with
minimal external components for up to 50% savings in board space in always-on
applications.

The MAX20075 and MAX20076 in peak
current mode also claim the lowest IQ of just 3.5 µA in the low-power operating
mode, which is key to meeting the stringent OEM IQ consumption requirements of
100 µA per module. The converters enable low noise operation via pin-controlled
spread spectrum and fixed 2.1-Mhz operation to meet CISPR 25 Class 5 EMI
compliance.

The MAX20075 and MAX20076 are available with a low
minimum on-time mode operation, which allows the converters to support large
input-to-output conversion ratios. The MAX20075 and MAX20076 meet AEC-Q100, are
available in a 3 x 3-mm TDFN package, and operate over the –40°C to 125°C temperature
range.
