n 20-Lead TSSOP Package n n n n The LT®8710 is a synchronous PWM DC/DC controller
with a rail-to-rail output current monitor and control. The
LT8710 is ideal for many types of power supply topologies
and can be easily configured for boost, SEPIC, inverting,
or flyback configurations. n 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. …
