Boost Controller Accessories

Photo of the 4-Channel Boost Controller for Diodes' AL3065 The AL3065 from Diodes is a 4-channel boost controller with outstanding efficiency for WLED backlight applications. It can function between input voltages of 4.5 V to 33 V. With an external resistor, the four channels' current may be easily set to range from 20 mA to 400 mA. 1.5 percent of channels are currently matched (typical). Its operational frequency is programmable between 0.1 MHz and 1 MHz. Direct PWM dimming, PWM to analogue dimming, and DC to analogue dimming are the three dimming modes that the AL3065 can offer. Cycle by cycle current limit, soft start, UVLO, programmable OVP, OTP, open/short LED protection, Schottky diode short and open protection, inductor short-circuit protection, and VOUT short protection are just a few of the robust protective features available.
