Description
The TPP2020 is a simple, easy to use, 2-A output, synchronous,
step-down,
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
