Beschreibung
Qorvo's ACT41000 is a programmable output, low noise, DC-to-DC buck converter with auxiliary bias supply regulators. This synchronous step-down voltage regulator supports a wide input voltage from 4.5 to 40 V and integrates both the high side and low side MOSFETS. These 50 m? RDSON transistors, driven by the optimized 5V self-biasing, enable high efficiency to reduce power losses.The product's main buck converter can be dynamically programed to an output voltage between 3 and 24 V in 12.5 mV steps via the I2C interface or analog feedback. It also can dynamically program output current between 0 and 4 A in 256 steps via the I2C interface in a constant-current (CC) operation mode. The main buck operates in a proprietary current mode control that supports external clock syncing for switching frequencies between 450 kHz and 2.25 MHz and spread-spectrum. ACT41000 has built-in iDAC for Bias Detection and automatic system level bias threshold trigger for PA Vdrain bias applications. The product also integrates a 5 V / 350 mA mini-buck converter and a 20 mA AUX LDO.ACT41000 is available in a 32-pin 5 mm x 5 mm QFN package with a power-optimized footprint and exposed pad for improved thermal performance.
