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 de-  
liver 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 fac-  
tory-programmable and an optional external resistor can be  
used to set LED current to user programmable values.
