Description
The LT®3964 is a dual synchronous step-down DC/DCconverter with I2C interface designed to operate as aconstant-current and constant-voltage source and is idealfor driving LEDs. The fixed frequency and peak currentmode topology result in stable operation over a wide rangeof supply and output voltages.
Features
Wide Input Voltage Range: 4V to 36Vn Two Independent 1.6A/40V Synchronous Bucksn I2C Interface for Internal True Color PWM™ Dimming(8192:1), Analog Dimming and Fault Reportingn 1000:1 External True Color PWM Dimming and10:1 External Analog Dimmingn PMOS Switch Driver for PWM and Output Disconnect
Typical applications
- Industrial
- Medical
- Automotive Lighting
- Constant-Current, Constant-Voltage Source
