XR2681完全替代FP6298

The XR2681 is a high frequency, high
efficiency DC to DC converter with an
integrated 6A, 40mΩ power switch capable
of providing an output voltage up to 24V.
The fixed 600KHz allows the use of small
external inductions and capacitors and
provides fast transient response. It
integrates Soft start, Comp,. only need few
components outside.
It can output 6V 2A、9V 1.3A for single
battery input. If Vbat=3.6V, it can output 6V
2.5A、9V 1.5A at good heat dissipation
condition.
