The Seeed Studio XIAO RP2040 is as small as the Seeed Studio XIAO SAMD21 but it's more powerful. On one hand, it carries the powerful Dual-core RP2040 processor that can flexible clock running up to 133 MHz which is a low-power microcontrollers. On the Seeed Studio XIAO RP2040 there is also 264KB of SRAM, and 2MB of on-board Flash memory which can provide more program to save and run. On the other hand, this little board has good performance in processing but needs less power. All in all, it is designed in a tiny size as small as a thumb(20x17.5mm) and can be used for wearable devices and small projects. #RP2040 #PICO #XIAO #SeedStudio

Buck-Boost Switching Regulator IC Positive Adjustable (Fixed) 6.5V (11.5V) 1 Output 6A 22-PowerWFQFN The MAX25239/MAX25240 are small, synchronous, buck-boost converters with integrated H-bridge switches. These ICs provide a fixed-output regulation voltage and an externally adjustable output voltage in the 3V to 20V range with an input voltage above, below, or equal to the output regulation voltage. The ICs have typical 8.2A and 10A input current limit options and can support continuous load currents up to 6A depending on the input-to-output voltage ratio and operating frequency. It also has a wide input voltage range of 2V to 36V. The MAX25239/MAX25240 have three switching frequency options: 2.1MHz, 400kHz, and 200kHz. The 2.1MHz high switching frequency allows small external components and reduced output ripple, and guarantees no AM band interference, while the 400kHz or 200kHz switching frequency offers better efficiency and relieves the power consumption concern. The SYNC input allows three operation modes: skip mode with ultra-low quiescent current, forced fixed-frequency PWM operation, and synchronization to an external clock. The IC also includes spread-spectrum frequency modulation to minimize EMI interference. The MAX25239/MAX25240 feature a power-OK (POK) indicator, undervoltage lockout, overvoltage protection, cycle-by-cycle current limit, and thermal shutdown. The ICs are available in small, 4.25mm x 4.25mm x 0.75mm, 22-pin FC2QFN and 5.00mm x 5.00mm x 0.75mm, 18- pin FCQFN packages. Key Features Wide 2 V to 36 V input voltage range Synchronous buck-boost topology for seamless step-up and step-down conversion Delivers up to 6 A continuous output current Adjustable output voltage from 3 V to 20 V (device variant includes fixed output configuration options) High conversion efficiency with integrated low-RDS(ON) MOSFETs 400 kHz switching frequency with spread-spectrum option for reduced EMI Very low 95 µA quiescent current in standby and 10 µA shutdown current Integrated protection features including overvoltage, short-circuit, thermal shutdown, and undervoltage lockout (UVLO) Power-Good (PGOOD) output for power monitoring AEC-Q100 qualified for automotive applications Operating junction temperature range: −40°C to +150°C Compact 22-pin FC2QFN (4.25 × 4.25 mm) package #MAX25240AFFFVY #AnalogDevices #BuckBoostConverter #DCDCConverter #PowerManagement #AutomotiveElectronics #AECQ100 #SwitchingRegulator #EmbeddedSystems #AutomotivePower
