Intersil EL6204CWZ-T7

Драйвер лазерного диода (CD/DVD)4,5 В ~ 5,5 В

Overview

The EL6204CWZ-T7 is a push-pull oscillator used to reduce laser noise. It uses the standard interface to existing ROM controllers. The frequency and amplitude are each set with a separate resistor connected to ground. The tiny package and harmonic reduction allow the part to be placed close to a laser with low RF emissions. An auto turn-off feature allows it to easily be used on combo CD-RW plus DVD-ROM pickups. If the APC current is reduced such that the average laser voltage drops to less than 1.1V, the output and oscillator are disabled, reducing power consumption to a minimum.The current drawn by the oscillator consists of a small utility current, plus the peak output amplitude in the positive cycle. In the negative cycle the oscillator subtracts peak output amplitude from the laser APC current.The EL6204CWZ-T7 part is available in the space-saving 6 Ld SOT-23 package and is specified for operation from 0°C to +70°C.
