Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Mingjiada Corporation has been supplying and recycling TI LP8869QPWPRQ1 High Integration 3-channel 120mA Automotive LED Driver for a long time, brand new and original, quality assurance!

Description of LP8869QPWPRQ1

The LP8869QPWPRQ1 is a highly integrated, low EMI, easy-to-use LED driver with a DC-DC converter that supports boost and SEPIC mode operation. The device is available with four or three high-precision current sinks that can be combined for higher current capability.

The DC-DC converters feature adaptive output voltage control based on the LED forward voltage. This feature minimises power consumption by adjusting the voltage to a low enough level under all conditions. To reduce EMI, the DC-DC supports spread spectrum of the switching frequency and external synchronisation of dedicated pins.The LP886x-Q1 uses a wide range of adjustable frequencies to avoid interference in sensitive frequency bands.
