Programmable regulator with seven channels claims lowest noise
The SLG51000 programmable regulator power management IC (PMIC) is aimed at high-end smartphone cameras and sensors with a PSRR of 73dB at 1MHz and output voltage noise of 10µV (rms). Each LDO channel provides from 475mA to 800mA with a quiescent current of less than 1µA for the entire device in shutdown.
System power designers face stringent noise budgets when designing advanced sensor systems or high-end camera modules for consumers that demand the highest quality images from their smartphones, digital cameras or other smart imaging devices, and chip makers have been increasing the number of channels that can be supported in a single device to same board area. Seven channels is currently the leading channel density for a programmable regulator.
“The success of our CMIC design capabilities following the acquisition of Silego Technology,” said John McDonald, VP of Marketing, CMBU, Dialog Semiconductor. “This CMIC’s advanced features demonstrate Dialog’s excellent power management design strengths coupled with Silego’s proven CMIC platform, characterized by product flexibility, fast support and the GreenPAK designer software platform. The SLG51000 is one of several key new products in our accelerated business growth strategy moving forward.”
Working with the SLG51000, engineers can create a variety of functions and control logic for applications such as custom power sequencing, fault signaling, input conditioning and glue logic. All of this can be configured graphically thanks to the IC’s unique GUI-based development software, adding to the ease-of-use advantage of the SLG51000 during development.
“With camera performance becoming one of the key differentiators of high-end smartphones, device manufacturers need to deliver the absolute best image quality from their image sensors within increasingly compact devices and are facing tighter noise budgets as a result. The SLG51000 is cutting-edge when it comes to meeting those noise budgets, with the best LDO performance available for imaging and sensor applications on the market today,” concluded McDonald.
The SLG51000 is sampling now and will be in production in the second half of 2019.
