PIN CONFIGURATION
DESCRIPTION
The CAT3636 is a high efficiency quad-mode fractional
charge pump that can drive up to six 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. The multi-fractional
charge pump supports a wide range of input voltages
from 2.5V to 5.5V.
The EN/SET logic input functions as a chip enable and a
“1-wire” addressable interface for control and current
setting of all LEDs. Three groups of two LEDs can be
configured with independent LED currents between
0.25mA and 32mA.
The device is available in a tiny 16-lead TQFN 3mm x
3mm package with a max height of 0.8mm.
The 1.33x charge pump with two fly capacitors is a
patent pending architecture exclusive to Catalyst
Semiconductor.
