Detailed Description
The AL3069Q is a high-efficiency 60V boost controller including four 80V high-precision current sink channels and fault diagnostics for LED backlight applications.
Boost with built-in adaptive voltage control operates over a wide input-voltage range from 4.5V to 60V. Its operating frequency can be adjusted from 100kHz to 1MHz.
The four channel current is simply programmed with an external resistor. The current match between any channels is ±0.5% (typical).
Extensive fault diagnostic and robust protection features include 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, VOUT short protection, and fault indicator (FAULTB) pin, which are designed for automotive applications to improve system robustness.
The AL3069Q is available in the TSSOP-16EP (Type DX) and UQFN4040-16/SWP (Type UXB) packages. It is qualified to AEC-Q100 Grade 1 and is automotive grade to support PPAPs.
