TEXAS INSTRUMENTS TPS549A20RVET 直流-直流开关同步降压稳压器, 可调, 1.5V-20V输入, 600mV-5.5V/15A输出, 1 MHz, VQFN-28 新
The TPS549A20 is a small-sized, synchronous buck converter with an adaptive on-time D-CAP3 control mode. The device offers ease-of-use and low bill-of-material count for space-conscious power systems.
This device features high-performance integrated MOSFETs, accurate 0.6-V reference, and an integrated boost switch. Competitive features include very-low external-component count, fast load-transient response, auto-skip mode operation, internal soft-start control, and no requirement for compensation. The device also features fault report via PMBus to simplify the power supply design
A forced continuous conduction mode helps meet tight voltage regulation accuracy requirements for performance DSPs and FPGAs. The TPS549A20 is available in a 28-pin VQFN-CLIP package and is specified from –40°C to 125°C ambient temperature.
