BD550FHG
●General Description
LED driver BD550FHG supports both isolated and non-isolated devices.
IC enables simple design of low-power electrical converters.
With switching
MOSFET and current detection resistor as external devices, it enables more freedom in design.
Since the peak current control is utilized, peak current is controlled in each cycle, application excels wide bandwidth and transient response.
BD550FHG includes various protective functions such as soft start function, burst function, per-cycle over current limiter, VCC over
voltage protection and overload protection.
An external latch pin (COMP pin) i...
