Description

The AIC2510 series are step-down monolithic PWM converters for delivering 3A at fixed voltages of 3.3V, 5.0V, 12V and using an external divider to adjust output voltage from 1.8V to 30V with excellent line and load regulation.
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 AIC2510 provides optimum output voltage accuracy and fast load transient response.
