The APW7128 is the high power and high efficiency
boost converter with an integrated 30V FET ideal for LCD
panel backlighting applications. 30V output voltage allows
for 8 high-power LEDs in series, and 3.5A inductor
current limit allows for more LED strings connected in
parallel. The low 0.5V feedback voltage offers higher
efficiency in WLED driver applications. The wide input
range from 2.7V to 21V made APW7128 a perfect solution
for various applications such as LCD monitor and
portable devices. The OVP pin monitors the output voltage
to protect IC during open load and FB pin short circuit
operations. The APW7128 provides the ALS pin to
simplify the interface to an ambient light sensor for automatic
dimming. The APW7128 is available in the thermally
enhanced DFN-10 lead 3mm x 3mm package.
