High efficiency charge pump with I2C interface (with photo)

The TPS60250 can drive up to five white LED's main display and two white LED's sub display, which can adjust the constant current size to maintain the consistency of the intensity. TPS60250 with adaptive charge pump mode and very low dropout current regulator, in the single lithium-ion battery input voltage range to achieve high conversion efficiency. I2C provides four enable inputs to simplify the on-off control of individual displays. To reduce the operating current when using a secondary display LED, the device also provides fully independent operation in the secondary display LED. Features: 3 ~ 6V input voltage range; 1x and 1.5x charge pump; I2C supports fully programmable current; 64 dimming step, the maximum 25mA (main and sub display group); 4 dimming step, the maximum 80mA (DM5 for auxiliary applications); Sub-LED current match up to 2% (100μA each) at light loads; 750kHz charge pump frequency; continuous 230mA maximum output current; x mode switching; built-in soft-start and current limit function; turn-on detection; 16-pin 3mm × 3mm QFN package.

Blind Rivet

Steel rivets are an important material used to connect or fix metal components, and the basic structure consists of two semi-cylindrical heads and a handle with a gradually tapering diameter. When in use, one end of the steel rivet is inserted into the rivet hole, and the other end is knocked to make it bulge on the inside surface, forming a circular sealing connection part or inserting it into the rivet hole to tighten. Due to the strong connectivity, low air resistance and versatility of steel rivets, it has a wide range of applications, including machinery manufacturing, automobiles, ships, electrical appliances and other fields.
