| | | Buck-Boost Controller Acts as UPS-on-a-Chip |
| Renesas Electronics has announced a pair of 80V DC-DC controllers that support the extra voltage margin needed for data center servers, 48V telecom and rugged industrial equipment. The ISL81801 buck-boost controller acts like a “UPS on a chip” by enabling bidirectional current flow (forward or reverse) using constant-voltage and constant-current regulation. |

| | | Measuring Soil Moisture with ADCs |
| How does capacitance relate to gardening? Here, Jeff Bachiochi steps through the math and science of capacitance, with insights on how capacitor functionality plays a role in successive approximation ADCs. He then applies MCU-based ADC tech to measure the amount of moisture in his garden’s soil. |
