Introduction

AI Translation

With the trend of better lighting homogeneity, highcurrent LEDs are often used in automotive front and rear lamps with lighting diffusers and light-guides. Meanwhile, in order to meet strict EMC and reliability requirements, linear LED drivers are popular in automotive applications. However, it is a challenge to deliver high current for linear LED drivers with integrated power transistors. The TPS92830-Q1 device is an advanced automotive-grade high-side constant-current linear LED controller for delivering high current using external N-channel MOSFETs. The device has a full set of features for automotive applications and is compatible with a wide selection of N-channel MOSFETs.

Each channel of the TPS92830-Q1 device sets the channel current independently by the sense-resistor value. An internal precision constant-current regulation loop senses the channel current by the voltage across the sense resistor and controls the gate voltage of the N-channel MOSFET accordingly. The device also integrates a two-stage charge pump for low-dropout operation. The charge-pump voltage is high enough to support a wide selection of Nchannel iMOSFETs.
