TI’s Introduces New Automotive LED Lighting Controller putting the energy in Designers’ Hands

Achieve higher power, better reliability and thermal dissipation in automotive LED lighting systems by picking out a controller and external MOSFET (PRNewsfoto/Texas Instruments Incorporated)

Texas Instruments (TI) on December 01, 2019, introduced the initial 3-channel high-side linear automotive light-emitting diode (LED) controller without internal MOSFETs giving designers greater flexibility for their lighting designs. TheTPS92830-Q1’s novel architecture enables higher power far better thermal dissipation than conventional LED controllers, and are generally particularly helpful for automotive LED lighting applications that want good performance and reliability.

Conventional LED drivers integrate the MOSFET, which limits designers’ opportunity to customize features. The real key style of driver, designers often must make significant design modifications to have the desired system performance. The?TPS92830-Q1 LED controller’s flexible onboard features give designers the freedom to select the best MOSFET because of their system requirements. Utilizing this type of new approach, designers can speedier and efficiently optimize their lighting power designs for automotive system requirements and desired dimming features.

Key features and benefits

  • Flexibility:?The?on-chip pulse-width modulation (PWM) generator or PWM input enables flexible dimming. Designers may use either the analog control or PWM to deal with an output current more than 150 mA per channel, to power automotive rear combination lamps and daytime running lights.
  • Improved thermal dissipation:?By pairing the LED controller using an external MOSFET, the designer is capable of doing the required high power output while distributing the energy towards the controller and MOSFET to avoid system overheating. By retaining linear architecture, the?TPS92830-Q1 provides improved electromagnetic interference (EMI) and electromagnetic compatibility (EMC) performance.
  • Greater system reliability: Advanced protection and built-in open and short detection features help designers meet original equipment manufacturer (OEM) system reliability requirements. The output current derating feature protects the external MOSFET under high profile conditions to be sure system reliability.

The?TPS92830-Q1 expands TI’s extensive portfolio of LED drivers, design tools and technical resources that really help designers implement innovative automotive lighting features.
