The PT7744C from Texas Instruments is a 20A booster designed to complement the PT7712 integrated switching regulator (ISR). This component operates from a 3.3V input voltage and is intended for applications requiring increased current capacity.
The PT7712 ISR, which the PT7744C supports, offers a programmable output voltage ranging from 1.3V to 2.05V, selected via a 4-bit code compatible with Intel VRM specifications. The PT7744C booster extends the current handling capability of the PT7712, making it suitable for microprocessor and DSP applications that demand higher core or I/O logic supply voltages.
This booster is housed in a space-saving, solderable copper package, designed for surface-mount (SMD) applications. Its integration with the PT7712 provides a robust power solution for demanding electronic designs.
