CMIC product targeted at high-end smartphone cameras; highlights combined strength of Dialog's power management IP and the programmable CMIC platform
LONDON, UK / ACCESSWIRE / May 15, 2019 / Dialog Semiconductor Plc (XETRA:DLG) a provider of highly integrated power management, audio, AC/DC power conversion, charging, and Bluetooth(R) low energy technology, today announced its latest Configurable Mixed-signal Integrated Circuit (CMIC) device with industry-leading low dropout (LDO) regulator performance, the SLG51000. The SLG51000 features the highest Power Supply Rejection Ratio (PSRR) and lowest output voltage noise of any programmable multi-channel LDO on the market, making it ideal to power advanced camera and sensor systems.
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. The SLG51000 exceeds the power performance requirements for such applications, compared to current market solutions which have significantly higher output voltage noise and relatively low PSRR especially at high frequency.
"Today's launch of the SLG51000 highlights 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 an awesome GreenPAK(TM) designer software platform. The SLG51000 is one of several key new products in our accelerated business growth strategy moving forward."
The SLG51000's technical specifications put it at the forefront for imaging and sensor power solutions. It provides industry-leading PSRR of 73dB at 1MHz and the lowest output voltage noise of 10µV (rms). Each of the 7 channels from the LDO regulator provide from 475mA to 800mA output current capability, and a low quiescent current of less than 1µA for the entire integrated circuit (IC) during shutdown. This small, integrated power solution reduces board space, while configurable output voltage settings, sequencing and resources satisfy multiple project requirements to reduce redesign, sourcing and qualification time.
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. For more information on the SLG51000, visit;
