Graphics LCD based on Microcontroller

The LCD reference design is developed using the Kinetis KL28Z through the standalone peripheral module FlexIO. The polling method is used to copy data from SRAM or flash to FlexIO's shifter buffer. Image Kinetis board is powered by an ARM® Cortex-M0, providing up to 96 MHz CPU performance besides supporting ultra-low power. KL28Z's FlexIO emulates…

High Power LED Controller

The LDS9003 is a 3-channel and LDS9001 is a 1-channel LED junction temperature monitor and control device intended for use in high power LED solid state lighting applications. It connects directly to a LED anode and the PWM input of available high power HB drivers to real-time adjust LED current to meet maximum LED temperature.…

Low Power and Turns Count Sensing with the Angle Sensor IC

This article discusses the uses of the A1337 in battery-powered automotive and non-automotive applications with the need of the sensor to function in multiple mission modes. Automotive Systems Requiring Sensor Operation Even in Key-Off Conditions Certain automotive angle sensing applications require the ability to track angular position even in key-off conditions. In the key-off state,…

1W to 5W LED Driver

This reference document describes a built and tested for a 1 to 5WLED driver forMR16 LED replacement. The circuit is proposed for driving HB--LED (high--brightness LED) in a variety of lighting applications but is configured in size and features for an MR16 LED replacement. Configurations like this are found in 12 Vac / 12 Vdc…

PIC24FV16KM202 CLASS D AMPLIFIER

Class D amplifiers have become a popular audio amplifier topology due to their high efficiency and subsequent low cost. The high current output stage is implemented using binary switches, resulting in minimal heat generation and power loss. This allows for the power supply, heat sink and overall physical size of the amplifier to be minimized.…
