Description for the LP8860-Q1

The LP8860-Q1 is an automotive high-efficiency LED driver with boost controller. It has 4 high-precision current sinks that can be controlled by a PWM input signal, an SPI or I2C master, or both.

The boost converter has adaptive output voltage control based on the headroom voltages of the LED current sinks. This feature minimizes the power consumption by adjusting the voltage to the lowest sufficient level in all conditions. A wide-range adjustable frequency allows the LP8860-Q1 to avoid disturbance for AM radio band.

The LP8860-Q1 supports built-in hybrid PWM and current dimming, which reduces EMI, extends the LED lifetime, and increases the total optical efficiency. Phase-shift PWM reduces audible noise and output ripple.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
