FP7172 Overview
The FP7172 is an open loop, current mode, control LED driver IC. The FP7172 can be programmed to operate in either a constant frequency or constant off-time mode. It includes an 15 450V linear regulator which allows it to work from a wide range of input voltages without the need for an external low voltage supply.
FP7172 Key Features
- Switch mode controller for single switch LED drivers
- Enhanced drop-in replacement to the FP7172
- Open loop peak current controller
- Internal 15 to 450V linear regulator
- Constant frequency or constant off-time operation
- Requires few external ponents for operation
