The LT8710EFE#PBF is a synchronous PWM DC/DC Controller with a rail-to-rail output current monitor and control. It is ideal for many types of power supply topologies and can be easily configured for boost, SEPIC, inverting, or flyback configurations. The LT8710's rail-to-rail output current monitor and control allows the part to be configured in current limited applications such as battery charging. The FLAG pin can be used as a power good indication or C/10 indication allowing for accurate bulk and float battery voltages. The LT8710's switching frequency range can be set between 100 and 750kHz using an external resistor or synchronized to an external clock. It also features innovative EN/FBIN pin circuitry that allows for slowly varying input signals and an adjustable under voltage lockout function. The pin is also used for input voltage regulation to avoid collapsing a high impedance input supply. Additional features such as frequency foldback and soft-start are integrated.
