Suggested Component for Optics Driver application

 -Hi there,

I am looking for some assistance in finding a component that will fit my new application. I am currently working on a PWM driver and have been looking into the viability of multiple components. I will include the specs as follows:

Laser Driver IC:

 - Supply Voltage: 5V (MAX)

 - Driver Current: 150 mA

 - Modulation/Brightness Control: PWM

 - Low Power IC

 - Small SMT package (7.5 mm x 7.5mm scale)

 - Load: Three LEDs chained in series (Forward Voltage ~ 1.2V) and a ballast resistor to choke the current 

Cheers!!! Appreciate any help I can get!
