3A EcoSpeed TM Step-Down Regulator with LDO and Ultrasonic Power Save
POWER MANAGEMENT Features
Description
The SC410 is an integrated, synchronous 3A EcoSpeedTM step-down regulator. It incorporates Semtech’s advanced, patented adaptive on-time architecture to achieve bestin-class dynamic performance using point-of-load applications. The input voltage range is 5.5V to 24V with a programmable output voltage from 0.75V up to 7.5V. 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 200kHz to 1MHz, allowing the designer to reduce external LC filtering and minimize light load (standby) losses. Additional features include cycle-by-cycle current limit, soft start, input UVLO and output OV protection, and over temperature protection. The open-drain PGOOD pin provides output status. Standby current is less than 10μA when disabled. The device is available in a low profile, thermally enhanced MLPD 3 x 3mm 10-pin package.
