TP78LXX-1 Datasheet, PDF (1/3 Pages) Toppower Electronic Technology Limited – Wide Input Non-Isolated & Regulated Single Output

TP78Lxx-1 Series
DESCRIPTION： _{Wide Input Non-Isolated & Regulated Single Output}
TP78LXX-1 series switching regulators are ideal replacement for TP78xx linear regulators
and LDOs. The efficiency of up to 97% means that very little energy is wasted as heat so
there is no need for any heat sinks with their additional space and mounting costs. They are
widely used in industrial control, instrumentation, and electric power applications.
