ASYNCHRONIES BOOST FOR 10 WLED DRIVER  
DESCRIPTION  
FEATURES  
The A8167A-020 is a step-up DC/DC converter  
specifically designed for driving white LEDs with a  
constant current. The internal MOSFET can  
support up to 10 White LEDs for backlighting and  
OLED power application, and the internal soft start  
function can reduce the inrush current. The  
A8167A-020 uses current mode, fixed frequency of  
approximately 1.0MHz architecture to regulate the  
LED current through an external current sense  
resistor. The low feedback voltage of 200mV can  
minimize power dissipation.  
VIN Operating Range : 2.5V to 5.5V  
Internal Power N-MOSFET Switch  
Wide Range for PWM Dimming  
(100Hz to200kHz)  
1.0MHz Switch Frequency  
200mV Feedback Voltage  
1.2A SW Current Limit  
Minimize the External Component Counts  
Internal Compensation  
Over Voltage Protection  
Available in TSOT-26 and DFN8(2x2)Packages  
Other features include current limit protection,  
thermal shutdown protection, under-voltage lockout  
(UVLO), and over-voltage function.
