300-W/20-A buck-boost dc-dc converters optimized for 24-V inputs
TDK Corporation announces the addition of 20A 300W rated models to the i7C non-isolated DC-DC converter series. These buck-boost board mount power modules have been optimized for 24V input with a range of 9 to 36Vdc and can be adjusted from 8 to 24V. The i7C topology enables a seamless transition from buck (voltage reduction) […]
UPS provides long back-up times via lithium-iron-phosphate batteries
Falcon Electric, Inc. introduces its lightweight SL LiFePO4 UPS family with lithium iron phosphate (LiFePO4) batteries that feature three to four times longer runtimes over lead-acid-based UPSs. Falcon’s 1 to 3kVA SL UPS features lithium iron phosphate batteries that provide maximum reliability and service life. Unlike other lithium-ion battery types, Falcon’s LiFePO4 batteries are safe as the lithium iron phosphate cathode material […]

High-power current sense resistors meet automotive quality standards
Bourns, Inc. announced the addition of nine new models to its existing AEC-Q200 compliant Model CSM2F High Power Current Sense Resistor Series. Bourns designed the new series as efficient, reliable, cost-effective, and accurate measurement solutions for the battery management systems (BMS), industrial control, and other high current applications. Current sense resistors are growing in popularity due to […]
What is a “Joule Thief” DC-DC converter?
In some applications, it can be useful to drain almost all of the energy of a single-cell battery, well below the voltage where the battery is usually considered fully discharged or “dead.” That’s when a Joule Thief dc-dc converter can be attractive. The name implies that the dc-dc converter is stealing Joules of energy from […]
Single-/Multi-cell solar harvester increases runtime in wearable and IoT applications
Designers of space-constrained designs can now significantly increase runtime with the MAX20361 single-/multi-cell solar harvester with maximum power point tracking (MPPT) from Maxim Integrated Products, Inc. . The industry’s smallest solar harvesting solution is ideal for space-constrained applications such as wearables and the emerging internet of things (IoT) applications. Designers are often challenged with the […]
Next-gen BMS goes wireless, with proprietary protocol and functional safety compliance
Because today’s battery management systems (BMS) are wired, the common source of cable failures – wire harnesses and connectors – becomes a warranty and functional safety issue. With the launch of a wireless BMS that features the first independently assessed functional safety concept, Texas Instruments hopes to revolutionize electric vehicle (EV) BMS. By removing the […]
80 V buck-boost battery charging controller integrates MPPT and I2C
Analog Devices, Inc. introduced the LT8491 buck-boost battery charging controller that features Maximum Power Point Tracking (MPPT), temperature compensation, and an I2C interface for telemetry and control. The device operates from input voltages above, below, or equal to the regulated battery float voltage. The LT8491 offers three selectable Constant Current Constant Voltage (CC-CV) charging profiles, […]
