Part Number: LP8545 I have a backlight driver based on LP8545. The circuit is virtually identical to Typical Application (1) in the datasheet except Vsync is not used and tied to ground, FILTER is tied to ground with a 10k resistor, and PWM is tied to…
Part Number: LP8545 Other Parts Discussed in Thread: LP8556 , TPS61177 , TPS61187 Hi guys,
My customer wants to use the LP8545 but they have a question. They need to enable the Iset pin to set the current threshold, but according to the datasheet the Iset…
Other Parts Discussed in Thread: LP8545 , LP8556 I have used the LP8545 on a design and like it. Have a new design where I have two LED strings. The load on each is about 110mA with a voltage of 8.1V to 9.3V. I think i can get there if I load share three…
Other Parts Discussed in Thread: LP8545 I am having issues with the LP8545 backlight display driver. The I2C interface is attached and VDDIO is connected to 3.3V. However, I am using it in PWM mode. The I2C interface is not used but the signals are pulled…
Other Parts Discussed in Thread: LP8545 Hi all,
I am building a simple circuit to control an embedded-DisplayPort LCD screen (60Hz, LP097QX1-SPA1), using the LP8545 to power the backlight. May I ask if the Vsync signal on the LP8545 must be connected to…
