1. Solution name: Wide voltage 12-100V electric vehicle charging power supply application solution H6215L

2. Solution Brand: Huihai Semiconductor

3. Program Overview:

Electric vehicles have become an important means of transportation for more and more people due to their convenience, environmental protection and high cost-effectiveness. When traveling, we often encounter situations where mobile phones or other electronic devices need emergency charging. At this time, we can use electric vehicle mobile phone chargers to solve this problem. They are plug-and-play and charge quickly.

This article introduces the application of power supply for USB mobile phone chargers in electric vehicles. H6215L, a high-efficiency DC-DC step-down constant voltage chip launched by Huihai Semiconductor, can be applied to this solution and plays an important role in the safe, stable and efficient operation of the charger power supply system. H6215L supports wide voltage input of 12-100V and 2A continuous current, and is widely compatible with mainstream digital products on the market. The chip has high output voltage accuracy, which can be controlled within ±5% constant voltage accuracy, and has line loss compensation function, which is lacking in similar chips on the market, and can solve the problem of output voltage being pulled down due to large output line loss. At the same time, H6215L has built-in multiple protection functions, which can avoid overvoltage, overcurrent, short circuit, high temperature and other situations during the charging process.

4. Features of the solution:

1. Low power consumption, low ripple
