Overview

Datasheet AC/DC Drivers AC/DC Controller IC for non-dimmable LED lighting 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 overvoltage protection and overload protection.
An external latch pin (COMP pin) is provided, so that latch stopping (OFF) can be set by external signals.
This function is available as overheating protection and over output voltage protection.
The PWM switching frequency is fixed at 65 kHz.
A frequency hopping function is included which contributes to low EMI.
