3 / 26 page Ver1.0 3 LD1022 16 Channel Constant Current LED Driver DESCRIPTION LD1022 is designed for LED displays with output current gain control. LD1022 contains a serial buffer and data latches, which convert serial input data into parallel output format. At LD1022 output stage, sixteen regulated current ports are designed to provide constant current sinks for driving LEDs within a wide range of Vf variations. FEATURES • 16 constant current output channels • Constant current output range: 5mA ~ 70mA • Output current adjustable through an external resistor • 8-bit programmable output current control • Output current accuracy: - between channels: ±1.0% (25mA < Iout < 70mA) ±1.3% (3mA < Iout < 24mA) - between ICs : ±3.0% • 25MHz clock frequency • Fast response of output current, Pulse width: 50nS • 3V ~ 5V supply voltage • Pb-free Package: SSOP24 (150) with two kinds of pin assignments PIN CONNECTION (TOP VIEW) GND SDI CLK LE OUT0 OUT1 OUT2 OUT3 OUT4 OUT5 OUT6 OUT7 VDD R-EXT SDO OEB OUT15 OUT14 OUT13 OUT12 OUT11 OUT10 OUT9 OUT8 1 2 3 4 5 6 7 8 9 10 11 12 24 23 22 21 20 19 18 17 16 15 14 13 BLOCK DIAGRAM ORDERING INFORMATION -40°C to 85 °C 24 SOP LD1022-SP -40°C to 85 °C 24 SSOP LD1022-SS TA PACKAGE PART NUMBER |
