TD8213
General Description
Features
The TD8213 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 TD8213 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 TD8213
provides the ALS pin to simplify the interface to an
ambient light sensor for automatic dimming. The TD8213
is available in the thermally enhanced DFN-10 lead
3mmx3mm package.
