    LT3952HFE#PBF Product overview

    The LT3952HFE#PBF is a current mode step-up DC/DC Converter with an internal 60V 80mR DMOS power switch. The LT3952 is specifically designed to drive high power LEDs in multiple configurations. It combines input and output current regulation loops with output voltage regulation to operate as a flexible current/voltage source. Programmable switching frequency with optional spread-spectrum modulation provides EMI reduction, while still allowing optimization of the external components for efficiency or component size. The LED current is programmable with an external sense resistor and can be adjusted from zero to full scale with a voltage at the CTRL pin. The external PWM input provides LED ON/OFF control and 4000:1 dimming ratio and an internal PWM generator delivers the efficiency of PWM dimming to standalone or I/O limited applications.
