| A power delivery network of DCM DC-DC converters can be used independently or with downstream point-of-load ZVS buck and buck boost regulators to support efficient power delivery. These scalable, high-efficiency DC-DC converters also provide superior power system performance and connectivity from a variety of unregulated power sources to the point of load.

| The TPS546D24A is a highly integrated, non-isolated DC/DC converter capable of high frequency operation and 40A current output from a 7-mm x 5-mm package. Two, three, and four TPS546D24A devices can be interconnected to provide up to 160 A on a single output. The device has an option to overdrive the internal 5-V LDO with an external 5-V supply via the VDD5 pin to improve efficiency and reduce power dissipation of the converter.

| Renesas has introduced the HIP2211 and HIP2210, a new pair of 100V half-bridge MOSFET drivers. The HIP2211 is a next-generation pin-compatible upgrade to Renesas’ popular ISL2111 bridge driver, while the new HIP2210 offers a tri-level PWM input to simplify power supply and motor drive design. The HIP2211 and HIP2210 are suitable for 48V telecom power supplies, Class-D audio amplifiers, solar inverters, and UPS inverters.

| This reference design enables a wearable, optimised saturation of peripheral capillary oxygen (SpO2) and multi-sensor, multi-wavelength optical heart rate monitor (HRM). It uses AFE4420 device, which is a single-chip, bio-sensing front end for photoplethysmography (PPG) measurements. It supports up to four switching light-emitting diodes (LEDs) and up to four photodiodes to enable signal acquisition of up to 16 Phases.

| Coilcraft’s XGL6060 series of moulded power inductors offer up to 40% lower DCR than the previous inductors. The XGL6060 inductors also offer low AC losses, resulting in the best overall efficiency over a wide range of AC ripple current, says the company.

| Escalating concern over rising carbon dioxide (CO2) emissions is driving worldwide demand for pure-electric vehicle (EV) and hybrid-electric vehicles (HEV) in aerospace design. The airline industry is undergoing a similar evolution and is analysing the cost and performance benefits of electric-powered aviation. If air travel infrastructure costs can be driven down, it becomes feasible to expand air travel to underserviced and remote geographies.

| A new family of photovoltaic (PV) array simulators has been launched by Keysight Technologies. The company says that they are the first to deliver 2000 V and 20 kW of power in a 3U format, enabling engineers to maximise solar power conversion. Small increments in power production can impact profitability of solar power generation.
