The high-speed all-electric railroad locomotive uses a catenary-wire system and pantograph power-transfer arrangement, which appears to violate good engineering practice and should not work. Still, it does, transferring hundreds of amps via a contact point moving at over 100 miles/hour. Part 2 of this article looked at power issues and numbers related to the […]
PMICs optimized to handle multiple automotive HD camera modules
Renesas introduced its latest solution to streamline power supply design for automotive, expanding its support for automotive surround view cameras into the design of HD satellite cameras. The highly integrated ISL78083 PMIC reduces development cycles, bill of materials cost, and supply chain risks to simplify power supply design for use in multiple HD camera modules. The […]
Super-efficient dc-dc converters target fast-charging mobile device apps
Halo Microelectronics announced two new products that utilize switched capacitor architecture to deliver 98% efficiency DC-DC conversion, which outperforms traditional DC-DC converters by up to 10% efficiency. This higher efficiency significantly reduces the thermal dissipation in mobile devices such as smartphones, thus enabling more power to be delivered to the battery and resulting in a […]
Automotive display PMIC takes the place of four discrete ICs
Designers of automotive electronic systems can now increase the number of displays per vehicle while reducing design complexity by using the MAX16923 4-output display power IC with watchdog timer from Maxim Integrated Products, Inc. By replacing four or five discrete ICs with a single power management solution, the MAX16923 significantly shrinks solution size and makes it […]

High-isolation current sensors handle overload current bursts up to 20 kA
LEM has expanded its range of miniature, integrated circuit sensors for AC and DC isolated-current measurement with the introduction of their new HMSR series. Despite being a small size, these components can handle overload current bursts up to 20 kA (8-20 µs surge test profile), such as those that occur in photovoltaics applications, while still providing a […]
PMICs optimized to work with STM32MP1 Arm Cortex-A7 and Cortex-M4 core MCUs
With features including four DC/DC buck converters, a boost DC/DC converter, and six low-dropout regulators (LDOs), the STMicroelectronics STPMIC1 power-management IC (PMIC) satisfies the complex power demands of highly integrated application-processor based systems. The chip is optimized as a companion PMIC for ST’s STM32MP1* heterogeneous multicore microprocessors, which target a broad range of applications by integrating single […]
PMIC works with small outline, un-buffered DDR5-based DIMMs
Integrated Device Technology, Inc. introduced the industry’s first integrated power management IC (PMIC) developed for small outline and un-buffered DDR5-based dual in-line memory modules (DIMM) addressing a broad range of notebook, desktop and embedded computing platforms. IDT’s P8911 enables next-generation client platforms to take full advantage of DDR5 memory to realize greater performance, density and […]
Bridge brings better thermal transfer for high-speed, dense connectors
TE Connectivity (TE) is introducing its thermal bridge technology that can provide up to two times better thermal resistance over traditional thermal technologies such as gap pads or thermal pads. As systems like servers, switches and routers deliver higher speeds and grow more sophisticated, their power requirements are rising, leading to a need for new […]
Dimmable LED controller IC targets automotive lighting apps
Taiwan Semiconductor Co., Ltd. (TSC), a global manufacturer of discrete devices (diodes, MOSFETs) and power management ICs, has just introduced a highly integrated dimmable LED controller for automotive lighting in MSOP-10EP package and AEC-Q100 qualified. Samples and products are in stock and available. TS19501CB10H is a single channel LED driver with low-side-current sense and a device […]
