LT3508IFE#TRPBF is a high efficiency synchronous DC/DC converter integrated with a low dropout regulator, targeted for point-of-load (POL) buck-boost applications. It consumes only 50µA in NoLd mode and provides up to 96% efficiency. The converter operates from 4V to 5.5V input and provides regulated output from 0.8V to VIN. The LT3508IFE#TRPBF DC/DC is optimized for high power density applications which require regulated output voltages in the presence of large amounts of input voltage variation.

The basic operating principle of a DC/DC converter starts with the input voltage being stepped up or down to the required level by a boost converter, buck converter, buck-boost converter or flyback converter. The converter then regulates the output voltage by either linear regulation or pulse width modulation to provide an appropriate amount of current to the load. DC/DC converters can be used to convert a variety of input and output voltages depending on their application.

The LT3508IFE#TRPBF is a buck-boost converter and can be configured to provide a regulated output from 4V to 5.5V from an input of 0.8V to 6V. It offers the highest available power density for a converter of its type and offers up to 96% efficiency to minimize power loss. This device is designed for use in applications ranging from mobile phones, tablets and digital cameras to portable medical and instrumentation equipment.

The integrated linear regulator on the LT3508IFE uses constant-on-time (COT) control to regulate the output voltage. It offers fast transient response, which allows the device to rapidly respond to sudden changes in current draw. The device also offers programmable frequency, soft-start and low quiescent current. The device also includes an integrated overload protection feature to prevent the output from exceeding the programmed value in the event of an overload.

The LT3508IFE#TRPBF is a versatile and cost-effective DC/DC converter solution for a wide range of POL applications. It offers high efficiency and low power loss, fast transient response and integrated overload protection. This product is an ideal choice for mobile, medical and instrumentation applications requiring high power density, fast transient response and low power loss.
