CAT3643 Datasheet 3-channel Ultra High Efficiency Led Driver

Manufacturer: onsemi

Overview: CAT3643 3-Channel Ultra High Efficiency LED Driver.

General Description

The CAT3643 is a high efficiency fractional charge pump that can drive up to three LEDs programmable by a one wire digital interface.

The inclusion of a 1.33x fractional charge pump mode increases device efficiency by up to 10% over traditional 1.5x charge pumps with no added external capacitors.

Low noise input ripple is achieved by operating at a constant switching frequency which allows the use of small external ceramic capacitors.

Key Features

  • High Efficiency 1.33x Cha.
