I have spent at least an hour almost every day since the 80’s advancing my knowledge in electronics. Recently I brushed up my knowledge on LED fading secrets and attained something pleasant. Now, I’d ...

The IS32LT3959 is a single inductor, multi-topology controller with constant on-time for driving a ground referenced high-voltage LED string. This single channel switching LED driver integrates a PWM ...

The AT9919 is a hysteric, buck, and high brightness LED driver with high-side current sensing. It is basically a PWM controller which uses buck topology to drive LEDs. It operates from an input ...

Most engineers are quite familiar with typical low-power-indicator LEDs, whether they be surface-mount or the classical through-hole packages. All that's needed to use them is a voltage source and a ...

How a single LED driver can support buck, boost, and buck-boost topologies. Design details for each topology type. How such drivers work in automotive and machine-vision designs. The breadth of LED ...
