High efficiency: A multi-mode, forced- frequency-resonant digital controller IC for SMPS applications Infineon Technologies AG launches the XDP™ digital power XDPS21071, the first flyback controller in the industry with zero-voltage switching (ZVS) on the primary side to achieve high efficiency. This controller is aimed at fast-charging applications such as USB-PD or QuickCharge. Light-load efficiency is optimized for variable output application. The XDPS21071 is a high-performance digital flyback controller with an integrated dual-MOSFET gate driver and a 600 V depletion startup unit. The primary-side controller drives a high-voltage external MOSFET in a flyback topology and an external low-voltage MOSFET to create a pulse for achieving ZVS condition at the high-voltage MOSFET. It supports fixed-frequency switching up to 140 kHz. The patented forced-frequency-resonant (FFR) switching scheme is implemented by means of a digital algorithm, which is configurable via parameter settings (UART port is included) to meet application requirements and the conversion efficiency of international regulatory standards (i.e., EU CoC version 5 Tier 2 and DoE Level VI). Ease of design and system optimization are made possible thanks to the intelligent, self- adaptive multi-mode operation that matches each line/load conditions with the best-fit operational mode (i.e., FFR, CrCM, burst mode) for unparalleled system performance. Hereby ZVS operation enables for lowest switching losses. Highest system performance is achieved by only a minimal adder in BOM cost. This controller comes with adaptive overcurrent protection. It is lead-free and RoHS compliant.

Renesas Electronics’ High-Efficiency Power Management IC Adopted in Google Coral AI Products Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, announced its ISL91301B Power Management IC (PMIC) is designed into the latest Google Coral products. They include the Mini PCIe Accelerator, M.2 Accelerator A+E Key, M.2 Accelerator B+M Key, and System-on-Module (SoM). Google Coral integrates seamlessly into processes at any scale, helping designers create a variety of local artificial intelligence (AI) solutions for several industries. Google Coral technology enables advanced neural network processing for low-power devices. At the heart of Coral is the Google Edge Tensor Processing Unit (TPU) coprocessor, which is capable of performing four trillion operations per second (TOPS), using 0.5 watts for each TOPS (2 TOPS per watt). For example, it can execute advanced mobile vision models, such as MobileNet v2 at 400 FPS, in a power efficient manner. The Renesas ISL91301B PMIC offers a high efficiency and small footprint power solution that is ideal for cutting-edge, low power edge AI processors. The ISL91301B has quad buck regulator outputs, each delivering up to 4A (total 16A) with 94 percent peak efficiency. The PMIC leverages Renesas’ R5 Modulation Technology for quick single-cycle transient response, tuned compensation, and fast switching frequency.
