General Description
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 appli-
cations 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
