description
The family of highly flexible, easy to use PFM controllers is ideal for
the use in wide input range switching regulator applications.
An advanced PFM control scheme gives these devices the benefits of
PWM converters with high efficiency for heavy loads, while using very
low operating current for light loads to maintain excellent behaviour
with output load variation.
The switching circuits are suitable for topologies requiring low side
FET, such as boost, flyback, Sepic, etc. Depending on the utilized
topology the controllers are capable of producing regulated positive
or negative output voltage.
Operating from 3V to 60V supply and in temperature ranges from
-40°C to 125°C the device is well suited for automotive applications.
Requiring a minimum number of external components, these regula-
tors are simple to use and cost-saving.
Self-protection features include an overload detection circuit, an
overtemperature shutdown under fault conditions and an under-volt-
age lockout.
