TPS54617 

3V to 6V input, 6A synchronous buck converter

illustrate   As a member of the DC/DC regulated SWIFT family, TPS54617 low input voltage high output current synchronous buck PWM converter offers the same features in a small package TPS54610 higher switching frequency. Included in the listed features with the substrate is a true, high-performance, voltage-error amplifier capable of selecting output filtered inductor and capacitor components in transient conditions and maximum flexibility; an undervoltage latching circuit to prevent start-up until the input voltage reaches 3 volts; An internal and external setup of slow start circuitry to limit inrush current, and a power-good output processor/logic reset is useful, fault signal and power supply sequencing. The TPS54617 is available in a thermally enhanced 34-pin QFN (UV-resistant) PowerPAD package, eliminating bulky heatsinks.   characteristic   30 m and high efficiency MOSFETΩ switch at 6 −A continuous output Adjustable output voltage 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 Synchronization to 1.6MHz Protect the load by peak current limiting and thermal shutdown Small 3.5 mm × 7 mm packages and similar layouts are available to TPS54610 reduce board area and total cost
