TP78xx-2 Series
DESCRIPTION
:
Wide Input Non-Isolated & Regulated Single Output
TP78XX-2 series switching regulators are ideal replacement for TP78xx linear regulators and
LDOs. The efficiency of up to 92% 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.
