EL6203
FN7218.2
Laser Driver Oscillator
The EL6203 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 pick-
ups.
One external resistor sets the oscillator frequency. Another
external resistor sets the oscillator amplitude. 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 bias
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.
This part is pin-compatible to the EL6201. It is superior to the
EL6201 in several ways: It has up to 100mA output
capability, it is more power-efficient, it has less harmonic
content, and it has an auto shut-off feature activated at 1.1V.
The part is available in the space-saving 5-pin SOT-23
package. It is specified for operation from 0°C to +70°C.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J STD-020C.
1 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
