Integrates pulse width modulation, skip mode, and current mode architectures into a single system.

Maxim Integrated Korea has launched the 'MAX20073' and 'MAX20074', pin-compatible buck converters ideal for automotive infotainment and advanced driver assistance system (ADAS) applications. The MAX20073/74 boasts the industry's lowest electromagnetic interference (EMI) and outstanding efficiency.

The MAX20073/74 offers significantly higher power efficiency across the entire operating range compared to competing products. It supports ultra-low standby current with minimal EMI and reduces interference affecting subsystem functions in compact solutions. Along with Maxim's proprietary Spread Spectrum feature, the SYNC IN function reduces EMI radiation, helping designers easily meet EMI requirements. Furthermore, it integrates Forced Pulse Width Modulation (PWM), Skip Mode, and Current Mode architectures into a single unit, dramatically improving system quality and performance while enabling easy design of the entire system.

Back-end Point of Load (POL) buck converters such as the MAX20073/74 supply highly precise voltage to multiple power rails added with the increase in state-of-the-art functionality. The output voltage precision of Maxim buck converters is ideal for applications with demanding processor and memory voltage requirements. The output voltage is factory preset, allowing the output voltage tolerance to be set to a range of ±1.5% without the need for expensive external resistors with 0.1% precision. The converter integrated circuit (IC) also adheres to strict safety standards. It operates at low input voltages over a wide temperature range while maintaining high precision and minimizing radio frequency interference (RFI). The MAX20073/74 is available in a small 3mm x 3mm 10-pin TDFN-EP package, reducing system space and bill of materials (BOM) costs.

Warren Tsai, Business Management Director of Maxim Integrated’s Automotive Business Unit, said, “Designers need buck converters that meet increasingly demanding requirements, such as solution miniaturization, specific voltage regulation precision, and improved efficiency. The MAX20073/74, the latest addition to Maxim’s low-voltage, compact POL buck converter family, is a solution that meets all of a system’s power requirements and EMI prerequisites.”
