As a family member of the DC/DC regulated SWIFT, the TPS54617 low input voltage high output current synchronous step-down PWM converter offers the same functionality as the TPS54610 and higher switching frequencies in a small package. Included in the listed features with substrate is a true, high-performance, voltage-error amplifier capable of selecting output filtering inductor and capacitor components in transient conditions and with maximum flexibility; an undervoltage lockout circuit to prevent start-up until the input voltage reaches 3 volts; An internal and external setup of a slow-start circuit to limit inrush current, as well as a power good output processor/logic reset useful, fault signal, and power sequencing.

The TPS54617 is available in a thermally enhanced 34-pin QFN (UV Resistant) PowerPAD package, eliminating bulky heat sinks.

characteristic

• 30 meters and high efficiency MOSFETΩ switches continuously at 6 - A
• The adjustable output voltage is as low as 0.9 V with 1% accuracy
• External compensation design flexibility
• Wide PWM frequency: fixed 350 kHz, 550 kHz, 280 kHz or adjustable to 1.6 MHz
• Sync to 1.6MHz
• The load is protected by peak current limit and thermal shutdown
• The small 3.5 mm × 7 mm package and similar layout reduce board area and total cost with the TPS54610
