Tiny DSLR Camera Power Solution Extends Battery Runtime

Dialog Semiconductor announced a compact multi-channel power management IC (PMIC) for power supply solutions in applications like DSLR, mirrorless cameras, handheld point-of-sale terminals, and multi-cell Li-ion battery applications.

DA6102’s high efficiency allows longer operational run times in 2S Li-ion battery applications and less heat dissipation for space-constrained and tightly-enclosed consumer devices, according to Dialog.

The DA6102 features two buck regulators, one buck-boost regulator, one high-current buck controller, and two always-on LDOs.

The chip’s extremely low RDSon FETs are said to enable efficiency as high as 94 percent for buck and buck-boost regulation. This high level of integration and efficiency, combined with a high switching frequency operation of up to 3 MHz, minimizes the PCB size and external component count and height, delivering an impressive 50 percent space saving over competing solutions.

An I2C interface enables flexibility and easy configuration of the output voltage, switching frequency, power sequencing, and fault protection. Most features are also configurable by OTP for simple output voltage and start-up sequence setup.

“The DA6102 has already been adopted by major OEMs in the industry and will start volume production later in 2017, which is a strong endorsement of the competitiveness of this device,” said Paul Wheeler, Vice President ASSP Mobile Systems at Dialog. “We are increasingly looking to bring our leading PMIC technology from smartphones where we enjoy more than 20 percent market share today to exploit new markets with an increasing range of power standard products.”

Dialog also offers its SmartCanvasTM GUI to accelerate product development time using the chip. The device is available in a WLCSP package measuring just 2.97 x 3.375 mm and available now through Avnet.
