ACT510x 23V Buck-Boost Converter with Integrated MOSFETs BENEFITS and FEATURES GENERAL DESCRIPTION Buck-Boost Converter with 4 Integrated Switches The ACT510x is a buck-boost converter with 4 inte- grated MOSFETs. It offers a high efficiency, low com- Wide VIN Range: 3.9V to 23V (No Dead Zone) ponent count, compact solution for a wide input voltage: Wide VOUT Range: 3.0V to 23V 3.9V to 23V Supports QC3.0 / USB PD + PPS output levels and transition times The 4 internal low resistance NMOS switches minimize Programmable Frequency: 125KHz, 250KHz, the size of the application circuit and reduce power 500kHz, and 1MHz losses to maximize efficiency. Internal high side gate 2V ~ 5.1V/100mA Programmable Output LDO drivers, which require only the addition of two small ex- Precision 0.5% Voltage Reference ternal capacitors, further simplify the design process. An advanced switch control algorithm allows the buck- +/-4% Output Constant Current Regulation boost converter to maintain output voltage regulation Programmable Output Voltage and Currents via 2 with input voltages that are above, below or equal to the both IC pins and I C output voltage. Transitions between these operating Programmable Soft-Start modes are seamless and free of transients and subhar- Programmable Safety Timer monic switching. Cycle-by-Cycle Current Limit Built in ADC for Temperature, Input and Output Volt- The ACT510x has been optimized to reduce input cur- age and Current monitoring rent in shipping, shutdown, and standby for applications which are sensitive to quiescent current draw, such as Thermal Regulation and Protection battery-powered devices. 25m FET from VIN to SW1 25m FET from SW2 to VOUT The ACT510x output voltage can be set between 3V ~ 2 35m FET from SW1 to PGND 23V which can be configured by either I C (ACT5101) 35m FET from SW2 to PGND or an external resistor divider (ACT5102). The output Thermally Enhanced 32-Lead 4mx4mm QFN constant current limit and cord compensation makes it flexible for any kinds of protocols such as USB PD, QC 3.0/4.0 etc. The system can be monitored and config- APPLICATIONS 2 ured by I C as well. The build-in ADC can be read for the information of input/output voltages and currents, Car Charger and the die temperature.
