Semtech | SC410MLTRT

The SC410MLTRT is an integrated, synchronous 3 A EcoSpeedTM step-down regulator. It incorporates Semtech’s advanced, patented adaptive on-time architecture to achieve best in-class dynamic performance using point-of-load applications. The input voltage range is 5.5 V to 24 V with a programmable output voltage from 0.75 V up to 7.5 V.

The device features an internal LDO and ultrasonic PSAVE mode for high efficiency across the output load range. Adaptive on-time control provides programmable pseudo-fixed frequency operation in continuous conduction and excellent transient performance. The switching frequency can be set from 200 kHz to 1 MHz, allowing the designer to reduce external LC filtering and minimize light load (standby) losses.
