Overview

The TPS92690 controller is a controller used in a Cuk topology for car battery (8 to 16Vdc) conversion to ~16V @ 32W for LED driving. This provides a low-cost, compact solution for automotive headlights.

Features
  • Non-isolated
  • Current regulation
  • Over-voltage protection for open LED
  • PWM dimming
  • Low EMI
