TPP2020-6TR 17-V Input, 2-A Synchronous Step-Down Voltage Regulator

　　The TPP2020 is a simple,easy to use,2-A output,synchronous,step-down,switch-mode converter with internal power MOSFETs.The TPP2020 provides a fast-transient response and supports both low equivalent series resistance(ESR)output polymer capacitors and ceramic capacitors with no external compensation components.TPP2020 offers a very compact solution to achieve a 2A continuous output current over a wide input supply range,with excellent load and line regulation.Protection features include over-current protection and thermal shutdown.The devices are available in a 6-pin TSOT23-6 package,and specified from–40°C to 125°C of ambient temperature.
