TPS6281xM/-Q1/-EP Step-Down DC/DC Converters

Texas Instruments TPS6281xM/-Q1/-EP 1A/2A/3A/4A Step-Down DC/DC Converters offer high efficiency and ease of use based on a peak current mode control topology. The TPS6281xM/-Q1/-EP pin-to-pin, 1A, 2A, 3A, and 4A synchronous step-down DC/DC converters automatically enter power save mode (PSM) at light loads to sustain high efficiency across the complete load range. The device supplies 1% output voltage accuracy in PWM mode, which helps develop a power supply with high output voltage accuracy. The SS/TR pin permits the user to set the start-up time or form tracking of the output voltage to an external source, supporting external sequencing of different supply rails and limiting the inrush current during start-up.
