L6462A transition-mode (TM) power-factor correction (PFC) controller cuts bill-of-materials (BOM) costs while enhancing efficiency, enabling consumer products and power supplies up to 250W to meet stringent eco-design norms.  The L6462A uses a current generator and shaper to produce a sinusoidal reference, instead of a conventional voltage sensor and analog multiplier, permitting boost-PFC converters without external voltage-divider components. In addition, the IC coordinates the PFC conversion cycles by sensing inductor demagnetization via the gate-driver output and hence requires no auxiliary inductor winding or interface components. In addition to lowering BOM, the L6462A’s innovative current shaping and demagnetization sensing minimizes distortion (THD) and enhances efficiency, particularly at intermediate and light loads. The new controller thus permits economical PFC with superior performance, targeting high-end battery chargers, power adapters, and power supplies for domestic an

Security is now a core part of product development. The EU’s Cyber Resilience Act (CRA) and Radio Equipment Directive (RED) have set mandatory cybersecurity and safety standards for connected digital and radio devices. The CRA is a new EU law requiring connected digital products to meet strict cybersecurity standards throughout their lifecycle, protecting users and reducing cyber risks. The RED is an EU regulation ensuring radio and telecom devices are safe, free from harmful interference, and equipped with essential security features for reliable wireless communication. As developers, integrating these requirements early helps build secure, reliable products that protect users, avoid costly penalties, and maintain market access. These regulations are designed to close security gaps early in the product lifecycle, ensuring devices are secure by design, regularly updated, and capable of resisting attacks. Non-compliance not only risks user safety and data integrity but can also lead to

Getting started with advanced STM32 debugging in VS Code with IAR C-SPYDebugging embedded systems gets harder as projects grow.At some point, breakpoints and variable windows stop being enough.

TSB192 dual op amps deliver very high precision for applications that need a wide operating-voltage range, with offset voltage of 20µV, temperature drift of 100nV/°C, and gain-bandwidth of 8MHz. While op amps with comparable offset voltage are usually precision devices that require a low-voltage supply, ST’s TSB192 can operate from any voltage between 4V to 36V. With 30µV maximum offset across the full temperature range and the low drift, the TSB192 minimizes reliance on compensation in signal-conditioning networks within industrial, automotive, healthcare, and consumer-electronic equipment. Drawing up to 1.9mA per channel extends the runtime of battery-operated equipment and rail-to-rail outputs maximize the available dynamic range. The precision and linearity of the TSB192 ensures repeatable performance in analog integrators and measurement circuitry of equipment such as temperature detectors, medical instrumentation, electronic scales, and industrial test instruments.

STMicroelectronics has announced two new high-speed half-bridge gate drivers that bring gallium-nitride (GaN) efficiency, thermal performance, and miniaturization to a broad range of power and motion-control applications. The STDRIVEG212 and STDRIVEG612 deliver tightly controlled 5V gate-drive signals to enhanced-mode GaN HEMTs, powered from a high-side voltage up to 220V or 600V respectively. The drivers are highly integrated, with high-side and low-side 5V linear regulators (LDOs), a high-side bootstrap diode, and protection including under-voltage lock-out (UVLO), in a compact QFN package. An integrated fast-startup voltage regulator stabilizes the supply voltage for the driver output stage, ensuring consistent gate control, while an embedded comparator turns off both GaNs on detecting overcurrent. Smart shutdown (SmartSD) automatically holds the switches off long enough to cool down and a fault pin provides overcurrent, overtemperature and UVLO reporting.The drivers are featured to
