LP5524 Parallel LED Driver with PWM Brightness Control in Micro SMD Package July 2007 LP5524 Parallel LED Driver with PWM Brightness Control in Micro SMD Package General Description The LP5524 is a highly integrated dual-zone LED driver that can drive up to four LEDs in parallel with a total output current of 100mA. Regulated high side internal current sources deliver excellent current and brightness matching in all LEDs. LED driver current sources are split into two independently controlled banks for driving secondary displays, keypad and indicator LEDs. Brightness control is achieved by applying PWM signals to each enable pin. Default LED current is factory-programmable and an optional external resistor can be used to set LED current to user programmable values.
