open-in-new Find other Buck converters (integrated switch)


is a family of pin-to-pin 1-A and 2-A high efficiency, easy-to-use synchronous step-down DC/DC converters. They are based on a peak current mode control topology. Low resistive switches allow up to 2-A continuous output current at high ambient temperature. In PWM/PFM mode, the automatically enter Power Save Mode at light loads to maintain high efficiency across the whole load range. The provide a 1% output voltage accuracy in PWM mode which helps design a power supply with high output voltage accuracy.

The available in a SOT583 package.
