Customers want in-vehicle uninterruptible power supply products to bring richer, more cool experiences than ever before. Designers are faced with even greater challenges: Optimization between advanced functions and small size, energy saving, and efficiency must be achieved.
The MAX20075 and MAX20076 use a peak current mode and have the industry's lowest quiescent current - only 3.5μA in low-power operation mode. This is key to achieving 100μA quiescent current per module required by OEMs. Converters are pin-enabled. Can spread spectrum or fixed frequency of 2.1MHz, support low noise work, meet the EMI requirements of CISPR 25 Class 5 standard. In addition, compared with non-synchronous devices working in AM frequency band, another 2.1MHz operating frequency and internal compensation The advantage is reduced solution size and bill of materials (BOM). The MAX20075 and MAX20076 support a minimum on-time mode that provides a large input-to-output conversion ratio. For example, allowing the IC to switch from Vbatt input to Vout less than 3V (2.1MHz operation Frequency) This means that one auxiliary power supply can be saved and the overall BOM cost can be reduced by $0.30 to integrate new features into the design for greater flexibility. The MAX20075 and MAX20076 are AEC-Q100 compliant and come in a 3x3mm TDFN package. Operating in the -40oC to +125oC ambient temperature range.
Key Benefits • Industry's lowest quiescent current: IQ is only 3.5 μA compared to 15-30 μA for traditional solutions; Flexibility allows more budget to be reserved for the system; Supports faster start-up times, Lower power consumption, and Short on-time • Highest peak efficiency: 91% peak efficiency compared to competitor products • Ultra-small solution size: 12-pin TDFN and side moisture-proof TDFN package (3mm × 3mm) with exposed pad; External components, 50% board space savings • Reduced EMI: Spread-Spectrum control and 2.1MHz internal fixed operating frequency to meet the EMI requirements of CISPR 25 Class 5 standard; to meet the requirements for uninterrupted processing capabilities in ADAS applications
