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.
CUI has announced the addition of four ultra-thin converter series to its isolated DC-DC converter line. The PYBJ3 series of isolated DC-DC converters are suitable for use in convection-cooled equipment and applications, including, datacom, telecom, remote sensor systems and portable electronics.
Maxim Integrated has announced the MAX25430, a 100W USB Power Delivery (PD) buck-boost controller and protector. The MAX25430 can reduce design size up to 40% compared to competitive solutions and offers the industry’s lowest cost for increasing the number of USB PD ports in vehicles, according to Maxim.
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.
Silicon Labs has introduced its new Si823Hx/825xx isolated gate drivers that offer faster and safer switching, low latency and high noise immunity capabilities. These attributes enable a compact PCB design to permit closer placement of the device to power transistors, says the company.
Shenzhen Xunlong has launched a tiny, $16 “Orange Pi Zero2” SBC with a new quad -A53 Allwinner H616 SoC, up to 1GB RAM, GbE, 802.11ac, BT 5.0, micro-HDMI, USB 2.0 and 26- and 13-pin GPIO headers.
