LT LT3595AEUHH#PBF

DC DC 稳压器3V5.5V50mA

Overview

The LT3595AEUHH is a high performance LED Driver designed to drive sixteen independent channels of up to 10 LEDs at currents up to 50mA. Series connection of the LEDs provides identical LED currents resulting in uniform brightness. Power switches, Schottky diodes, and compensation components are all internal, providing a small converter footprint and lower component cost. The high 2MHz switching frequency permits the use of tiny, low profi le inductors and capacitors. A fixed frequency, current mode architecture results in stable operation over a wide range of supply and output voltage.

A single external resistor sets the LED current for all sixteen channels, and dimming is then controlled for each channel by pulse width modulating the individual PWM pins. Relative current matching among the sixteen drivers is 8% and the PWM dimming range is 5000:1. The part is available in a 5mm x 9mm x 0.75mm 56-pin QFN package.
