Description

The family of highly flexible, easy to use PFM controllers E910.25 is ideal for the use in wide input range switching regulator applications.

An advanced PFM control scheme E910.25 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 E910.25 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  40C to + 125C the device E910.25 is well suited for automotive applications. Requiring a minimum number of external components, these regulators are simple to use and cost-saving.

Self-protection E910.25 features include an overload detection circuit, an overtemperature shutdown under fault conditions and an under-voltage lockout.
