The APW7228B is a high efficiency driver for 4 channels
of LEDs. It contains an adjustable-frequency currentmode PWM step-up controller, a 5V linear regulator, dimming control circuit and eight regulated current source
circuit.
The APW7228B is capable of driving typically 68 (4x17)
pieces of 3.5V/160mA LEDs. It contains 4 channels of
voltage controlled current sources with typical currents
matching of +1%, which compensate for the non-uniformity effect of forward voltages variance in the LED stacks.
To minimize the voltage headroom and power loss in the
typical multi-strings operation, the APW7228B features a
dynamic headroom control that monitors the highest LED
forward voltage string and uses its feedback signal for
output regulation.
The APW7228B features extensive protection functions
that include LED strings open and short circuit detections,
Output Over-Voltage Protection (OVP) and Over-Temperature Protection (OTP).
The APW7228B is available in TSSOP-16P, SOP-16, DIP16 and QFN4x4-16A package.
