ISL58303 Features The ISL58303 is a high-speed triple output laser diode driver
designed to support color field sequential laser light source
Pico projection modules. Outputs can be ganged together to
achieve peak total current greater than 3.6A. Output channels
are designed with independent programmable bias and
threshold adjustment to support a wide range of laser diode
manufacturers. The ISL58303 offers exceptional power
efficiency and a high degree of system integration allowing a
compact and cost effective system design. Complete triple programmable laser diode driver To assist with reduction of laser speckle, this laser diode driver
has a high frequency modulation input to modulate laser
pulses. This can be used to achieve outputs pulses of less than
1ns.
Interface to the system is accomplished via a high-speed serial
bus that is made up of SEN, SCLK and SDIO. Initialization of
internal registers after power-on reset, operational setup and
laser intensity data for each output channel are
communicated through this bus.
For laser operational safety, a hardware enable signal (CE) is
ANDed with an internal register bit. Both have to be asserted to
enable the device. This prevents an accidental fault causing an
unwanted laser output. 800mA maximum output current per channel 1200mA peak output current per channel Ganging of multiple channels as well as multiple chips can …
