Eight-rail power manager for camera modules
The Texas Instruments TPS65530ARSLR is an 8-output adjustable voltage converter designed specifically for digital still camera applications. It accepts a 1.5V to 5.5V input and delivers eight independently adjustable output rails, making it a single-chip power solution for the multiple supply voltages a camera sensor, image processor, and display require.
Input range and output flexibility
The 1.5V to 5.5V input range covers single-cell Li-Ion and multi-cell alkaline or NiMH battery stacks, as well as regulated 3.3V or 5V system rails. Each of the eight outputs is adjustable, so you can set independent voltages for the CCD/CMOS sensor, analog front end, DSP core, I/O, and display backlight without adding separate LDOs or switchers.
The 0.5 mm pitch demands a decent hot-air station and a steady hand; the pad layout is symmetrical, so pin 1 orientation is marked by a chamfer on the package corner.
The operating temperature range is -25°C to 85°C.
