CAT3616:LED Driver, Charge Pump, 6-Channel
The CAT3616 is a high efficiency 1x/1.5x fractional charge pump with programmable dimming current in six LED channels. To ensure uniform brightness in LCD backlight applications, each LED channel delivers an accurate regulated current. Low noise and input ripple is achieved by operating at a constant switching frequency of 1MHz which allows the use of small external ceramic capacitors. The 1x/1.5x fractional charge pump supports a wide range of input voltages from 3 V to 5.5 V with efficiency up to 91%, and is ideal for Li-Ion battery powered devices. Two groups of LEDs, main (MAIN1 to MAIN4) and sub (SUB1 and SUB2) are programmable through the ENM (active low) and ENS inputs. Independent current from 1 mA to 31 mA with a 1 mA step are set by toggling the ENM and ENS inputs. The enable EN input pin allows to shutdown the device with zero quiescent current.
