    On behalf of Anthony Armstrong: 
    The Silent Switcher technology can also be applied in a boost mode topology. I am sure you know that with boost converters, the internal switching in a monolithic die can be very large – depending on how much output current is needed by the load. Which is why we have a broad offering of boost controllers. That said, we do have a few monolithic silent switcher boost converters in development (typically have less than 3A outputs). That said, one example is our LT3922 - a monolithic, synchronous, step-up DC/DC converter with internal 40V, 2A power switches and an internal PWM generator. Its fixed frequency peak current mode control accurately regulates current within ±2% for a string of LEDs up to 34V. Its integrated PWM generator offers up to 128:1 dimming ratio. If dimming ratios of up to 5,000:1 are required, the LT3922 and an external PWM generator can accommodate these applications. The LT3922’s 2.8V to 36V input voltage range is ideal for a wide range of applications, including automotive, industrial and architectural lighting. The combination of a Silent Switcher topology and spread spectrum frequency modulation minimizes EMI concerns. For further information on these you will need to contact your local ADI sales contact to obtain further information on them.
