Diodes has introduced a 1A linear mode constant current LED driver designed to reduce the size and cost of general lighting products including flashlights, emergency lighting, garden lighting and poolside applications.
The highly integrated DLD101LED driver is packaged in an optimized small-sized flat DFN package, which saves designers a lot of board space and the high thermal efficiency of the package ensures higher power consumption than the SOT23IC.
The DLD101 integrates a unique "base-access pre-bias transistor" with an on-chip bias resistor that sets the LED current through a single external resistor without the need for additional boost transistors. In terms of bypass components, a high drain current 60VN channel MOSFET is used instead of a bipolar transistor to reduce the overall bias current.
The DLD101 not only reduces PCB area and external component count for LED driver solutions, it also completely eliminates the EMI characteristics of switching regulator solutions.
Barium titanate lead-free piezoelectric ceramics are important basic materials for the development of modern science and technology, which was widely used in the manufacture of ultrasonic transducers, underwater acoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic frequency discriminators, high voltage generators, infrared detectors, surface acoustic wave devices, electro-optic devices, ignition and detonation devices, and piezoelectric gyroscope and so on.
Application: military, ocean, fishery, scientific research, mine detection, daily life and other fields.
