Datasheet 4ch White LED Driver with Buck Boost …
Datasheet 4ch White LED Driver with buck - Boost (40 LED Maximum). BD81A44 MUV-M / BD81A44 EFV-M. General Description Key Specifications BD81A44 MUV-M/EFV-M is a White LED Driver with the capability of Operating Input Voltage Range to 35 V. withstanding high input voltage (35V Max). This Driver has 4ch Output LED Current Accuracy constant-current drivers integrated in 1-chip, where each channel DC/DC Oscillation Frequency 200 to 2200kHz can draw up to 120mA (Max), which is also suitable for high illumination LED drive. Furthermore, a buck - Boost current mode Operating Temperature Range -40 to +125 . DC/DC controller is also integrated to achieve stable operation LED Maximum Output Current 120mA/ch during power voltage fluctuation. Light modulation (10,000:1 PWM min pulse width @100Hz dimming function) is possible by PWM input.
