TPS54310-EP

The TPS54310-EP low input voltage high output current synchronous buck PWM converter integrates all required active components. The TPS54310-EP device is available in a thermally enhanced 20-pin TSSOP (PWP) PowerPAD package, which eliminates bulky heatsinks.

Features of the TPS54310-EP are:(1)controlled baseline;(2)extended temperature performance of -55 to 125;(3)enhanced diminishing manufacturing sources (DMS) support;(4)enhanced product-change notification;(5)qualification pedigree;(6)60-m MOSFET switches for high efficiency at 3-A continuous output source or sink current;(7)adjustable output voltage down to 0.9 V with 1% accuracy;(8)externally compensated for design flexibility;(9) Fast transient response;(10)wide PWM frequency: fixed 350 kHz, 550 kHz, or adjustable 280 kHz to 700 kHz;(11)load protected by peak current limit and thermal shutdown;(12)integrated solution reduces board area and total cost.
