MAX16841 LED driver
Maxim Integrated Products has introduced an offline LED driver for industrial, commercial and residential lighting applications such as retrofit dimmable LED lamps and universal LED bulbs.
The MAX16841 provides flicker-free dimming from maximum light intensity down to zero intensity with both leading-edge (triac) and trailing-edge (transistor) dimmers.
Constant frequency control is designed to optimise efficiency at both low- and high-AC line voltages.
The LED driver prolongs the life of LED lamps because it can operate without electrolytic capacitors; eliminating capacitors also saves space and cost, according to the company.
- Input range of 90VAC to 265VAC
- Temperature range of -40°C to 125°C
- Suitable for both high-AC line voltages (220VAC to 230VAC) and low-AC line voltages (100VAC to 120VAC)
This tutorial from Maxim Integrated Products explains the sensor signal chain for the most popular sensor transducer types for pressure, temperature, current, light and proximity sensing. It introduces the intricacies of selecting a signal path. Example circuits and block diagrams help the reader to select an optimal set of parts to meet his or her design needs.
This overview of industrial motor controls from Maxim Integrated Products highlights the differences and subsystems for DC motor, brushless DC and AC induction motors. An in-depth analysis of critical subsystems focuses on monitoring and measuring current; sensing temperature; sensing motor speed, position and movement; monitoring and controlling multi-channel currents and voltages; and high-accuracy motor control with encoder data interfaces.
This tutorial from Maxim Integrated Products discusses the expanding role that light-emitting diodes (LEDs) are playing in general lighting applications. It compares the performance of LEDs with that of other lighting technologies. It also analyses the main challenges of designing LED lamps that retrofit existing lighting systems.
Based on a µP-supervisor/watchdog IC (MAX6749), the circuit described in this application note from Maxim Integrated Products provides a latched failure indication in response to a loss of the input pulse stream.
