TPS92510DGQ

Драйвер светодиода, 1 выход, понижающий, 3.5В-60В (Vin), 2.5МГц, 58В/1.5A, HVSSOP-10.

The TPS92510DGQ is a 1.5A peak current-mode Step-down Converter with an integrated high-side MOSFET. It is specifically designed for driving high-brightness LEDs with a constant current. The tight-tolerance, 200mV internal reference voltage reduces power dissipation in the current-sense resistor. A dedicated pulse width modulation input pin allows linear control of the light output. It integrates a thermal fold back feature that reduces the average output current to ensure that the sensed LED temperature never exceeds a specific value, improving the reliability of the overall system. An integrated frequency synchronization feature allows a reduction of unwanted beat- frequencies in multi-string applications and simplifies EMI filtering. The adjustable input voltage UVLO feature accommodates the various deep discharge levels of multiple battery types.
