DC2049A

DC2049A is a LT3999EMSE low noise isolated power supply demonstration board. The DC2049A demonstrates how a power supply regulates two output voltage by using the LT®3999 and low dropout (LDO) regulators. The LT3999 is a monolithic push-pull DC/DC driver which features wide input range and small external passive components. The LT3999 has duty circle control for ΔVIN compensation which allows for a wide input voltage range and low LDO losses. TheDC2049A employs a push-pull topology that inherently provides a low-noise solution. The design is well suited to noise sensitive systems such as medical instruments, industrial sensing and control, data conversion and wide band communications.
