general description
the ta848 is a highly integrated low cost
current mode pwm controller, which is ideal
for small power current mode of offline
ac-dc fly-back converter applications.
making use of external resistors, the ic
changes the operating frequency and
automatically enters the pfm/crm under
light-load/zero-load conditions. this can
minimize standby power&..
