Beschreibung
The ACT510x is a buck-boost converter with 4 integrated MOSFETs. It offers a high efficiency, low component counts, compact solution for a wide input voltage range from 4V to 23V application. The 4 internal low resistance NMOS switches minimize the size of the application circuit and reduce power losses to maximize efficiency. Internal high side gatedrivers, which require only the addition of two small external capacitors, further simplify the design process. An advanced switch control algorithm allows the buckboost converter to maintain output voltage regulation with input voltages that are above, below or equal to the output voltage. Transitions between these operating modes are seamless and free of transients and subharmonic switching.The ACT510x output voltage can be set between 3V ~23V which can be configured by either external resistor divider or I2C. The output constant current limit and cord compensation makes it flexible for any kinds of protocols like USB PD, QC 3.0/4.0 etc. The system canbe monitored and configured by I2C as well. The building ADC can be read for the information of input/output voltages and currents, die temperature, and generic input signals.ACT510x integrated a 100mA LDO output with OCP/UVLO protection to provide power for the MCU and other peripheral components inside the system.The ACT510x operation frequency can be configured from 125 kHz to 1MHz, makes the system design flexible for components size and efficiency optimization. The ACT510x has been optimized to reduce input current for applications which are sensitive to quiescent current draw, such as battery-powered devices. The AC5101 is available in 32-pin, 4 x 4 mm FCOL QFN package.
