LM3409HVMY

Драйвер светодиода, 1 выход, понижающий, 6В-75В (Vin), 1A, MSOP-10.

The LM3409HVMY is a PFET Buck Controller for high power LED drivers. This controller offers wide input voltage range, high-side differential current sense with low adjustable threshold voltage and fast output enable/disable function and ideal for use as constant current sources for driving LEDs where forward currents up to 5A are easily achievable. The LM3409 use Constant Off-Time (COFT) 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.
