TCA62723FMG TOSHIBA CMOS Integrated Circuits Silicon Monolithic TCA62723FMG Three-Channel Constant-Current LED Driver The TCA62723FMG is an optimal constant-current LED driver for RGB pixel LEDs. This IC does not have to connect external resistance to each output in the case of most. The output current of 3ch is set up by one external resistance. Features Weight: 0.018 g (typ.) Power supply voltage range : 2.7 to 5.5 V Constant current range : 5 to 150 mA Low consumption current At the time of IC operation mode (Iout = 20 mA/DC) : 700 A (MAX) At the time of IC power-saving mode : 10 A (MAX) For anode common LED Package : SON10-P-0303-0.50 1 2010-06-10 TCA62723FMG Pin Layout (Top view) Assly in first half of year Assly in latter half of year (The 26th week from the first week) (The 53rd week from the 27th week) 10 VIN 10 VIN SHDN SHDN 1 1 OUT0 OUT0 CTL0 9 CTL0 9 2 2 OUT1 CTL1 OUT1 CTL1 3 8 3 8 OUT2 OUT2 CTL2 7 CTL2 7 4 4 GND REXT GND REXT 6 6 5 5 Terminal Description Pin Pin Function No. Name The shutdown signal input terminal. 1 SHDN In the case of level input, the IC becomes the power-saving mode. In the case of level input, the IC becomes the operation mode. The ON/OFF control signal of OUT0 Input terminal. 2 CTL0 In the case of level input, OUT0 is turned OFF. In the case of level input, OUT0 is turned ON. The ON/OFF control signal of OUT1 Input terminal. 3 CTL1 In the case of level input, OUT1 is turned OFF. In the case of level input, OUT1 is turned ON. The ON/OFF control signal of OUT2 Input terminal. 4 CTL2 In the case of level input, OUT2 is turned OFF. In the case of level input, OUT2 is turned ON. 5 GND Grand terminal. The output current setting resistor connection terminal. Resistance is connected with this terminal between GND. 6 REXT The output current does not flow when this terminal is opened. Excessive output current will destroy the IC if this terminal is connected to GND. 7 OUT2 Constant current output terminal. 8 OUT1 9 OUT0 10 VIN Supply voltage input terminal. 2 2010-06-10
