FUNCTIONAL DECRIPTIONS

The ACE711E is a high efficiency, high output voltage boost converter in a small package size. The

device is ideal for delivering 1-2A current when boosting up the output voltage. The device integrates

20V/2.5A switch FET and

operates in pulse width modulation (PWM) with 1MHz fixed switching

frequency. For operation details, please check the block diagram at the “Block Diagram” chapter. The duty

cycle of the converter is set by the error amplifier output and the current signal applied to the PWM control

comparator. The feedback loop regulates the FB pin to a low reference voltage (200mV typical), reducing

the power dissipation in the current sense resistor.
