General Description
The DE-SW0XX family of switch mode voltage
regulators are designed to be the easiest
possible way to add the benefits of switch-
mode power to a new or existing project. The
DE-SW0XX family is Pin-compatible with the
common 78XX family of linear voltage
regulators. They have integrated decoupling
capacitors, so external capacitors are not
generally necessary. Available voltages are
3.3, and 5 volts.
The DE-SW0XX family operates over a wide
input voltage range, from (Vout+1.3V) to 30v,
at up to one amp of continuous output current.
Efficiencies are up to 87% (Figure 2) Ripple is
less than 2% of output.
The DE-SW0XX family works on a
breadboard, making it an ideal solution for
prototyping and one-off circuits.
