A8160A
LED BACKLIGHT DRIVER
ASYNCHRONIES BOOST FOR 10WLED DRIVER
DESCRIPTION
FEATURES
The A8160A is a step-up DC-DC converter
specifically designed for driving white LEDs with a
VIN Operating Range : 2.5V to 5.5V
Internal Power N-MOSFET Switch
constant current.
Wide Range for PWM Dimming
The internal MOSFET can support up to 10 White
(100Hz to 200kHz)
LEDs for backlighting and OLED power application, 1.0MHz Switch Frequency
and the internal soft start function can reduce the 300mV Feedback Voltage
inrush current.
1.2A SW Current Limit
The A8160A uses current mode, fixed frequency of Minimize the External Component Counts
approximately 1.0MHz architecture to regulate the Internal Compensation
LED current through an external current sense Over Voltage Protection
resistor. The low feedback voltage of 300mV can Available in SOT-26 Packages
minimize power dissipation.
Other features include current limit protection,
