LED Drivers Ready For The Road

The AT9917 and AT9932 LED drivers target automotive lighting apps, i.e., head, tail and dome lights, indicators, and panel backlights. The AT9917 uses a peak-current mode control scheme to drive single switch converters and integrates a transconductance amplifier. It also includes a fault output using an external FET. The AT9932 employs a feed-forward current control scheme that achieves low susceptibility to input-voltage transients. Available in 24-lead TSSOPs, prices for the AT9917 and AT9932 are, respectively, $2.05 and $2.23 each/1,000. SUPERTEX INC., Sunnyvale, CA. (800) 222-9883.
