TLD5045EJ is the latest addition to Infineon's Power LED family. It is a DC/DC buck converter with highest integration levels and current capability of up to 700mA. Components are kept to a minimum thanks to the integrated switch, freewheeling diode and sense resistor. Integrated PWM capabilities mean the TLD5045EJ can also be used without a microcontroller. An integrated dummy current sink ensures that the BCM is compatible with halogen bulbs.
Features
- Simple buck driver with integrated switching transistor, diode and shunt
- Lowest external component count
- Up to 700mA output current
- Plug-in replacement for bulbs - TLD5045EJ+LED can behave like a standard halogen bulb
Applications
- Automotive interior and exterior LED applications
- Automotive bulb replacement solutions like LED rear fog light
- Center High Mounted Stop Light (CHMSL)
- Break and tail lights
- Daytime running lights and position lights
Application example - TLD5045EJ in a decentralized light module
