Diodes LED driver switches to tight current control
Diodes has employed new forms of current control in its latest LED driver ICs which it said is designed to increase the reliability of high brightness lamps, writes Richard Wilson.
The ZXLD1370 LED driver controller operates in buck, boost and buck-boost topologies.
It uses a new control loop structure and high-side current sensing to ensure accurate current control of LED strings.
The driver supports dimming through DC dimming and PWM dimming options. With a dedicated PWM input, the driver offers a 1000:1 dynamic dimming range at 1kHz.
