• 10% Higher Efficiency*
• 65% Smaller Package*
• No Additional Capacitors*
• No Added Cost*
• No Inductor

Catalyst's Quad-Mode® adaptive fractional charge pumps take LED driver performance to a new level by offering a 10% efficiency improvement and up to 65% smaller packaging*, without the need for an additional capacitor, and with no price premium.

Better than Inductors
The innovative, patented Quad-Mode charge pump architecture delivers the high-efficiency levels normally associated with inductor-based LED drivers, while eliminating the high-profile inductors and unwanted EMI.

Better than Three-Mode Charge Pumps
Most charge pump LED drivers offer three modes of operation corresponding to the ratio of the output voltage to the input voltage: 1x, 1.5x, and 2x. The Quad-Mode architecture adds a fourth mode of operation, 1.33x, without the need for the additional capacitor required by all other existing four-mode charge pumps. The 1.33x fractional operating mode also reduces the input switching currents seen at the battery, minimizing the overall supply noise.
