The MAXREFDES1247 is a miniature, 12V output, isolated power supply that can deliver up to 1A of load current.
The MAXREFDES1265 is a reference design showcasing the MAX7360 and MAX32625PICO with a low-cost, small-size keypad interface.
The MAXREFDES1277 reference design enables quick evaluation of the MAX17852/53 for 48V two-Wheeler battery management applications (BMS)
The MAXREFDES1213 is a reference design showcasing the MAX32630FTHR and MAX11311, as well as several other Maxim products, that demonstrates a small size, low-cost, portable electronic load (E-load) for testing power converters and PMICs.
The requirements for higher quality and performance in digital SLR cameras, DSC, and other 2S Li+ battery electronic equipment is increasing.
This reference design boosts a single-cell battery voltage input to a 10W output using the MAX16990 controller in bootstrapped mode.
The MAX16990 is a high-performance, current-mode, pulse-width mode (PWM) controller with 4μA (typ) shutdown current for wide input-voltage range boost converters/single-ended primary-inductor converters (SEPIC)
The MAXREFDES1273 is a Power-over-Ethernet (PoE) powered device (PD) and an active clamp forward DC-DC converter (ACFC) that delivers up to 850mA at 48V from 39V to 57V supply voltage
The MAXREFDES1209 operates over a 14V to 60V input voltage range to deliver output voltage regulated at 12V and up to 500mA of load current.
The MAX17596 is a peak-current-mode controller for designing the wide input-voltage flyback regulators.
Hardware configuration: Dialog Semiconductor DA14683 for master control, with BLE5.0
The schematic diagram is open source, you can see if there is anything worth learning from. This baseboard is designed for their previously launched H7 core board.
Supports various Cortex-M cores, can be used wirelessly in the local area network, and can be used remotely in the external network.
The product design is open source and very cool and beautiful.
The author opens up the schematic diagram and supporting Raspberry Pi code. The simulation bandwidth is already 30MHz, and the frequency response is very close to the theoretical simulation, with a difference of about 0.02dB between 1kHz and 30MHz.
ST has previously launched a board with a static current measurement range of 1nA - 100mA and a dynamic current measurement range of 100nA - 50mA, but it is not open source. This time it’s open source.
The very early model was a bit crude.
The schematic is in the appendix at the end of the document.
The most interesting part is the problem of energy collection without batteries. Currently, it provides energy collection by clicking buttons and solar energy collection. Ambiq Apollo3 for main control.
