Save 50% in board space with Maxim’s latest step-down converters

Maxim Integrated Products has release what it describes as ‘ultra-compact, pin-compatible’ step-down converters. The MAX20075 and MAX20076 have been created specifically for system designers looking to create ‘small and highly efficient’ 40V load dump-tolerant applications.

According to Maxim, its MAX20075 and MAX20076 offer the industry’s lowest quiescent current (IQ) and comes in an ultra-small size solution with integrated compensation. This is said to enable minimal external components that can lead up to 50% savings in board space. Maxim said this makes them ideal products for ‘always-on’ automotive applications.

In peak current mode, these devices are said to draw just 3.5µA in the low power operating mode, which is key to meeting the stringent OEM IQ consumption requirements of 100µA per module.

The converters are also designed to enable low noise operation via pin-controlled spread spectrum and fixed 2.1Mhz operation to meet CISPR 25 Class 5 EMI compliance.

Maxim also indicated that an added advantage of the 2.1Mhz operation and internal compensation is that it lowers the solution size and the bill of materials compared to a non-synchronous device that operates in the AM band.

The MAX20075 and MAX20076 are available with a low minimum on-time mode operation, adds Maxim, which should allow the converters to support large input-to-output conversion ratios. For example, Vbatt input to Vout of <3V at 2.1Mhz; this translates to not having to use a secondary supply, which reduces overall BOM cost by $0.30 to incorporate new functions into the design for greater flexibility.

The MAX20075 and MAX20076 are said to meet AEC-Q100, are available in a 3x3mm TDFN package, and operate over the -40°C to +125°C temperature range.
