MAX16833B
Description
The MAX16833, MAX16833B, MAX16833C, MAX16833D, and MAX16833G are peak current-mode-controlled LED drivers for boost, buck-boost, SEPIC, flyback, and highside buck topologies.
Key Features
- provides extremely fast PWM current switching to the LEDs with no transient overvoltage or undervoltage conditions
- In addition to PWM dimming, the ICs provide analog dimming using a DC input at ICTRL
- The ICs sense the LED current at the high side of the LED string
- In the MAX16833/C/G, the switching frequency can be dithered for spread-spectrum applications
- The MAX16833B/D instead provide a 1.64V reference voltage with a 2% tolerance
- This is a unique feature of the ICs
Applications
- Automotive Exterior Lighting: High-Beam/Low-Beam/Signal/Position Lights, Daytime Running Lights (DRLs), Fog Light and Adaptive Front-Light Assemblies
