Highly Efficient 2-10 LEDs Backlight Driver with 2 PWM Inputs
1 General Description
The AS3492 is an inductive highly efficient DCDC boost converter. The DCDC converter operates at a fixed frequency of 2MHz and includes soft startup to allow easy integration into noise sensitive RF systems. A predictable startup is guaranteed even with very low duty cycle PWM input signals. The voltage on the output capacitor is controlled to minimize ripple and to avoid any acoustic effects for low frequency PWM input signals.
The output of the DCDC converter is used for five current sources connected to up to 10 LEDs. If a current source is not required, it shall be connected to...
