The LTC3245IMSE#TRPBF is a monolithic dual-input/dual-output single-stage synchronous flyback dc-dc switching regulator that combines two independent switched-mode power converters in a single package. Both channels with power factor correction and up to 26-A output current. This dual-channel synchronous flyback regulator uses a single-stage architecture to minimize the number of external components and maximize efficiency. By providing two channels in a single package, the LTC3245IMSE#TRPBF allows customers to significantly reduce the component count and board area in their designs. It is ideal for portable applications that require two independent outputs with high current demands and short form factor.

The LTC3245IMSE#TRPBF is designed to support a wide range of applications. It can be used for battery-charge management, 12V applications, such as servers, storage and telecom systems, as well as distributed power systems. The device integrates high-side and low-side MOSFETs in addition to an inductor, all of which are housed in a tiny 36-pin package. This allows designers to significantly reduce the number of components required, enabling a shorter design cycle. The device supports a wide input-voltage range from 3.2–24V, allowing it to power from any input source, including USB ports and batteries. Additionally, the LTC3245IMSE#TRPBF features a power-good signal and programmable output voltage and current settings.
