Description

Switching frequency up to 150KHz is achievable thus allowing smaller-sized filter components. Internal current limit and thermal shutdown circuits provide protection from overloads. The internal precise reference combined with voltage feedback loop of AIC2511 provides optimum output voltage accuracy and fast load transient response.
