IMX50EVK: i.MX50 Evaluation Kit

Electric vehicle charger source program based on ATmega48PA chip, including PCB board

The charger program written with STM8S003 has positive and negative pulses throughout the process, anti-reverse connection, scheduled shutdown during charging, and negative pulses to repair the battery later.

45W USB-PD/PPS power adapter solution using EZ-PD™ PAG1 and CoolGaN™

This 45W Type-C PPS reference design uses Infineon's EZ-PD™ PAG1s and PAG1P controllers and CoolGaN™ 600V GIT HEMT. The solution complies with international energy efficiency standards including DoE Level 6/CoC Level 2, and its standby power can be as low as less than 30 mW. The solution is tested to CE standards defined by CISPR32 Class B and achieves a high board-side power density of 17.71 W/in3. This solution is designed for use with USB PD (including PPS), QC power adapters. Adapters covering traditional charging protocols including Apple Charging, BC1.2, QC 3.0 and Samsung AFC are also supported. PAG1S and PAG1P jointly provide low BOM cost, high-performance solutions compatible with PD/PPS/QC.

Open source audio amplifier

The power supply has a stable symmetrical +/- 40 V to ensure optimal performance.
Maximum power (THD 1%) approaches 100 W into 8 Ω load and 190 W into 4 Ω load (see measurements). All parts are through-hole, making it easy to build the amplifier. The design is completely symmetrical.

Schematic PCB

Wireless power supply and data transmission solution

This technology is suitable for products that are waterproof and dustproof or can be disassembled and cleaned. Taking the wall-breaking machine as an example, a temperature detection function is built into the cup body, and wireless power supply and data communication are used to transmit the temperature data to the host. Two wireless power supply architectures are available: a transparent transmission module architecture to facilitate product function upgrades, or an integrated main control chip architecture to streamline hardware costs.
