APE5039
40 Channel White LED Controller for LED Backlight
Features
- LED Open Detection
- Temperature Shutdown detection
- UVLO
General Description
The APE5039 are integrates Mosfet and 40 channel LED controller for LED backlight. It’s high accurate LED current 2% (60mA LED current) and wide input voltage range. The APE5039 has 40 Channel flexible PWM generators and independent 13 bits PWM brightness were control LED current for every channel. In addition; It's has one global/local high accurate 10 bit DAC which sets the LED current. It’s synchronization with TV Frame including VSYNC and Digital PLL method. The APE5039 own LED current modulation method including PWM mode and DC mode. When applications have flicker frequency issue and then can using the DC mode method eliminate flicker frequency problem. The APE5039 has two pins can be digital configurable DC/ DC feedback, that’s for control DC/DC architecture. As the same time; the device using programmable via SPI interface. The APE5039 owns HDR mode for modulation LED current. It’s build-in protection for safety; include LED short, LED Open, temperature shutdown protection and UVLO. The APE5039 is available in QFN 9x9-76 packages.
