ACT41000 Datasheet Low Noise Voltage Regulator

Manufacturer: Qorvo

Overview

ACT41000 Programmable Voltage, Programmable Current, Low Noise Voltage Regulator for RF Components Product Overview The Qorvo® ACT41000 is a low noise, dc-to-dc buck converter with a programmable output and auxiliary bias supply regulators.

This synchronous step-down voltage regulator supports a wide input voltage of 4.5 V to 40 V and integrates both the high side and low side MOSFETS of 50mΩ RDSON for high efficiency power conversions.

To power up a drain of GaN/GaAs Power Amplifiers (PAs), the ACT41000 supports a programmable output both in voltage and current (limit) setpoints and the device operates in constant-current (CC) and constant-voltage (CV) seamlessly.
