NexFET™ Power Block MOSFET Half Bridge: The CSD86350Q5D NexFET Power Block is a high-performance, 25-V half bridge designed for low duty cycle, high-current synchronous buck POL applications. The Power Block uses optimized silicon and advanced packaging to achieve over 2% higher efficiency than discrete MOSFETs in half the space. The higher efficiency results from a 20% reduction in power loss compared to discrete implementations.
Resources: Data sheet, EVM, video
- Ultra-low inductance SON 5x6-mm package up to 1.5MHz capable
- Half the PCB area vs. discrete implementations with 40-A max current capability
- Applications: Synchronous buck converters, high-frequency apps, high-current, low duty cycle apps, multiphase synchronous buck converters, POL DC/DC converters, IMVP, VRM, and VRD apps
CSD86350Q5: Price (1ku): $1.75 |

SymPol™ Transceiver: The SN65HVD96 operates with no errors if the twisted-pair signal wires are connected normally or reversed, allowing for error-free operation in applications where the signal wires may become inadvertently reversed during installation or maintenance. This correction is made internally so no intervention from the controller or operator is required.
Resources: Data sheet, block diagram, EVM
- Same pinout as RS-485
- Similar to RS-485, can be used for point-to-point, multi-drop, or multi-point networks
- High input impedance for up 32 nodes
SN65HVD96: Price (1ku): $1.20 – $1.35 |

SuperSpeed USB Transceiver with PIPE3 and ULPI Interfaces: The TUSB1310 is a complete USB 3.0 physical front-end solution that supports SuperSpeed (5Gbps), high-speed (480Mbit/s), full-speed (12Mbit/s) and low-speed (1.5Mbit/s). The adaptive equalization is based on the industry’s leading PCI Express GenII technology and enables receiver sensitivity of less than 50-mV differential peak-to-peak—twice as good as required by the specification.
Resources: Data sheet, application note, video
- Flexible, integrated spread-spectrum clocking
- Applications: Surveillance cameras, multimedia handsets, smartphone
TUSB1310: Price (1ku): $6.00 |
