ZSLS7025ZI1R

The ZSLS7025ZI1R is a constant-current Boost Converter designed for driving high-brightness LEDs. It is optimal for driving multiple white LEDs connected in series so that the LED current is uniform for better brightness and colour control. The wide input range and high output current enables diverse industrial and consumer lighting applications. The ZSLS7025 output current is adjustable via an external current sense resistor and can deliver stable constant output current from a few milliamps up to 2A or higher. The ZSLS7025 drives a constant current into the load. The control loop features a pulse frequency modulated (PFM) architecture that is inherently stable and does not need loop compensation. It supports pulse-width modulation (PWM) or linear voltage dimming, which allows flexible control of the LED luminance.
