1. SparkFun BabyBuck Regulator Breakout, 3,3V, AP63203
The SparkFun BabyBuck Regulator Breakout, 3.3V, AP63203, is a highly advanced electronics module designed as a compact synchronous buck converter. With a maximum output power of 2A and a fixed output voltage of 3.3V, this module is ideal for applications that require a reliable power supply. It supports input voltages ranging from 3.8V to 32V and integrates both a high-side and a low-side power MOSFET in a compact TSOT26 package. The board measures just 0.4 x 0.5 inches, making it particularly space-saving. The use of through-hole connections for input and output voltages facilitates easy connection to other components. Additionally, the integrated Frequency Spread Spectrum (FSS) technology significantly reduces electromagnetic interference, while specialized gate driver designs minimize ringing at the switching node. Protection features such as over-voltage protection and thermal shutdown ensure safe operation of the module.
- Compact design with minimal space requirements
- Maximum continuous output current of 2A
- Integrated Frequency Spread Spectrum (FSS) technology to reduce EMI
- Proprietary gate driver design to suppress switching noise
- Integrated protection features such as over-voltage protection and thermal shutdown.
2. SparkFun Pegelübersetzer Breakout - PCA9306
There are some boards that every engineer and maker should have on their desk, and this PCA9306 dual bidirectional voltage level translator breakout is one of them! Since different components sometimes use different voltage levels to communicate, voltage level translators can be key to ensuring that various components work together.
The PCA9306 is a dual bidirectional I2C bus and SMBus voltage level translator that operates on the low side from 1.2V to 3.3V and on the high side from 1.8V to 5.5V. Simply apply your low and high side reference voltages to VREF1 and VREF2 respectively, connect your I/O, and drive the enable pin high to enable bidirectional voltage translation without the need for a direction pin!
We have updated this classic board to use a new footprint, added a second ground pin, and broken out the enable pin.
