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
