The AAT3176 flash driver IC operates from a 2.7V to 5.5V input and provides up to 500mA of output current. The dual-mode charging pump maximizes power efficiency by supporting 1X and 2X operation and can be programmed in 16 unique steps via AnalogicTech's patented S2Cwire (Simple Serial Control) interface. It is the smallest package of the industry's 500mA flash driver IC - 20% smaller than its peers - the AAT3176 allows designers to create fairly small camera lighting solutions.
To achieve maximum design flexibility and minimize programming time, the AAT3176 uses individual external resistors to set maximum flash and film mode current. To protect the integrity of the device, the drive has a thermal management system including open and short circuit protection and an automatic soft start circuit. The load disconnect feature extends battery life by disconnecting the load during shutdown and reduces quiescent current to less than 1.0μA.
The AAT3351 is a high efficiency charging pump that can drive 4 white LEDs at 30mA each. The two-group mode fractional charge pump automatically switches between 1X and 1.5X modes based on input voltage, LED forward voltage, and load current for maximum efficiency. 1MHz switching frequency helps reduce external component size to the nearest school
To smoothly switch between brightness levels, this component uses AnalogicTech's S2Cwire serial digital interface to enable, disable, and set current to one of 32 levels. The LED current output accuracy is +10% and the LED current matching is 3%. The AAT3351 also adds an automatic soft-start circuit and built-in short-circuit protection.
Hybrid PCB Assembly = Hybrid Printed Circuit Board Assembly, which means the PCB Board need be mounted with SMT parts and THT parts. For such PCB Assembly job, SMT assembly will be done first, after checked well, then do THT assembly. Zhongfeng would manufacture the PCB boards follow the design file, source the components follow the BOM file and do the PCB assembly job follow the assembly drawing and the pick&place file. After PCB assembly done, the components would be mounted on the PCB boards tightly and connected each other through the copper circuits. We call such board as PCBA board or hybrid custom PCBA board.
Depends on the components assembly types, it have THT PCB assembly, SMT PCB Assembly , one sided SMT and THT PCB assembly, two sided SMT and THT PCB assembly.
Depends on the PCB type, it have Rigid PCB Assembly , Flex PCB Assembly and Flex-Rigid PCB Assembly.
Also we would call some PCB assembly types as Prototype PCB Assembly, Mass PCB Assembly , Turnkey PCB Assembly, LED PCB Assembly and BGA PCB Assembly , etc.
With our 15years professional experience, we are available for all types of PCB assembly service from prototype to mass production, available for 01005, 0201, 0.3mm BGA, 0.3mm QFP.
