Средства разработки интегральных схем (ИС) управления питанием TPS54A20EVM-770

The TPS54A20EVM-770 is an evaluation module for TPS54A20 synchronous step down converter. The TPS54A20 is a two phase, synchronous series capacitor buck converter designed for small size, low voltage applications from a 12V input rail. This 10A, SWIFT regulator synchronous dual phase converter evaluation module generates a 1.2V output voltage from nominal 12V input. The circuit is set up for default operation of 2MHz per phase. The EVM includes an on-board transient load circuit to allow fast transient testing. This evaluation module is designed to demonstrate the small printed circuit board areas that may be achieved when designing with TPS54A20 regulator. The high side and low side MOSFETs are incorporated inside TPS54A20 package along with gate drive circuitry. The low drain to source on-resistance of the MOSFET allows the TPS54A20 to achieve high efficiencies and helps to keep junction temperature low at high output currents.
