Abstract
RF PA circuitry and a DC-DC converter, which includes an RF PA envelope power supply and DC-DC control circuitry, are disclosed. The PA envelope power supply provides an envelope power supply signal to the RF PA circuitry. The DC-DC control circuitry has a DC-DC look-up table (LUT) structure, which has at least a first DC-DC LUT. The DC-DC control circuitry uses DC-DC LUT index information as an index to the DC-DC LUT structure to obtain DC-DC converter operational control parameters. The DC-DC control circuitry then configures the PA envelope power supply using the DC-DC converter operational control parameters. Using the DC-DC LUT structure provides flexibility in configuring the DC-DC converter for different applications, for multiple static operating conditions, for multiple dynamic operating conditions, or any combination thereof.
