TPP2020中文资料17-V Input, 2-A Synchronous Step-Down Voltage Regulator数据手册3PEAK规格书

描述 Description

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.
