The multipurpose module RG3000 is an isolated power amplifier that combines switching and linear topologies to achieve high efficiencies and linearity over a wide input voltage range. The switching power converter delivers power to the load from the input power source, while the linear power amplifier at the output section assists the load during the discharging phase of the operation. The RG3000 operates similarly to a linear power amplifier with a pushpull power stage. Specifically, during the PUSH phase the power OPAM delivers power to the load from the positive supply source through the output power transistor, and during the PULL phase it sinks power from the load through the complimentary power transistor to the negative power supply as is shown in Figure 1. The RG3000 needs only one power supply; its output is completely isolated from the input and offers very high efficiency and excellent linearity. The high efficiency is the product of the switching power transfer, while the linearity is due to the high open loop gain of both the converter and the linear amplifier.
