Renesas ZSLS7025

Beschreibung

The ZSLS7025, one of our ZSLS Family of LED control ICs, is a constant current boost converter designed for driving high-brightness LEDs. It isoptimal for driving multiple white LEDs connected in series so that the LED current is uniform for better brightness and color control. The wide inputrange and high output current enables diverse industrial, after-market automotive, and consumer lighting applications. The ZSLS7025 output current is adjustable via an external current sense resistor and can deliverstable constant output current from a few milliampsNup 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 inherentlystable and does not need loop compensation. The ZSLS7025 supports pulse-width modulation (PWM) or linear voltage dimming, which allowsflexible control of the LED luminance. The ZSLS7025 can operate in applications with a wide input voltage range from 5V to 100V. Anintegrated over-voltage protection (OVP) circuit protects the system, even under no-load conditions. The over-voltage protection is adjustable via external resistors R1 and R2.
