LT3710 - Secondary Side Synchronous Post Regulator

The LT3710 is a high efficiency step-down switching regulator intended for auxiliary outputs in single secondary winding, multiple output power supplies.

The LT3710 drives dual synchronous N-channel MOSFETs and achieves high efficiency. With leading edge modulation, it operates well with either primary side peak current or voltage mode control. It is synchronized to the falling edge of the transformer secondary winding and can be used in both single-ended and double-ended isolated power converter topologies. A high speed operational amplifier is incorporated to achieve optimum compensation and fast transient response. A user selectable discontinuous conduction mode improves light load efficiency.

The LT3710 is available in a thermally enhanced TSSOP-16 exposed pad power package.
