Mingjiada Supply Maxim Power Management IC, Supply MAX20029 Series Low Voltage Step Down DC-DC Converters

As demand for miniaturised, highly efficient and highly reliable power supply systems continues to rise in the automotive electronics, industrial automation and consumer electronics sectors, high-performance multi-channel power management ICs are becoming a key focus for design engineers. As a specialist electronic components supply chain service provider, Mingjiada Electronics has long supplied the MAX20029 series of low-voltage step-down DC-DC converters from Maxim (now part of ADI), providing highly integrated power management solutions for in-vehicle infotainment systems, ADAS sensor modules and industrial embedded devices.

[Maxim] MAX20029 – Automotive Applications, 4/3/4-Channel, Low-Voltage, Step-Down DC-DC Converters
The MAX20029/MAX20029B/MAX20029C power management ICs (PMICs) integrate four low-voltage, high-efficiency, step-down DC-DC converters. Each of the four outputs can be factory-set or resistor-set within a range of 0.7 V to 4.0 V. The MAX20029 features four 1.5 A channels, the MAX20029B features two 1.5 A/3.0 A channels, and the MAX20029C features four 1.5 A channels, with VOUT as low as 0.7 V. Operating at 3.0V to 5.5V, these PMICs are ideal for automotive point-of-load and back-end regulation applications. The MAX20029/MAX20029B/MAX20029C PMICs are housed in a 28-pin TQFN package with an exposed pad and operate within the automotive-grade temperature range of –40°C to +125°C.
