OB3375 Quasi-Resonant Buck LED Driver Controller

Name: OB3375 Quasi-Resonant Buck LED Driver Controller
Brand: On-Bright
SKU: OB3375

The OB3375 is a high-efficiency buck LED driver controller from On-Bright using quasi-resonant, peak-current-mode control for white-LED and LCD-backlight strings. A built-in transconductance amplifier gives accurate constant-current (CC) regulation, with HPWM current setting and LPWM low-frequency dimming (1%~100%), plus full protection (LED open/short, CS open, MOS/diode/inductor short, OTP, UVLO). SOP8.
