| Description | The LP8545 is a white LED driver with integrated boost converter. It has six adjustable current sinks which can be controlled by PWM input or with I2C-compatible serial interface. The boost converter ... |
| Features |
which make it possible to detect LED outputs with open or short fault. As well low input voltage and boost over-current conditions are monitored and chip is turned off in case of these events. Thermal de-rating function prevents overheating of the device by reducing backlight brightness when set temperature has been reached. LP8545 is available in National's LLP 24-pin package.
Features
■ High-voltage DC/DC boost converter with integrated FET ■ ■ ■ with four switching frequency options: 156/312/625/1250 kHz Configurable for use with external FET for applications needing higher output voltage ... |
