LM3409MY

Драйвер светодиода, 1 выход, понижающий, 6В-42В (Vin),1A, MSOP-10.

The LM3409MY is a PFET Buck Controller for high power LED drives. This controller offer wide input voltage range, high-side differential current sense with low adjustable threshold voltage and fast output enable/disable function. The LM3409 controller use Constant Off-Time control to regulate an accurate constant current without the need for external control loop compensation. Analogue and PWM dimming are easy to implement and result in a highly linear dimming range with excellent achievable contrast ratios. Programmable UVLO, low-power shutdown and thermal shutdown complete the feature set.
