Start-up IC for DC/DC-Converter Starts From 0.3V Input Voltage

NEU-ISENBURG, Germany - S-882Z is the part number of a new Charge Pump IC, introduced by Seiko
Instruments, which distinguishes itself by physical set-up from traditional
integrated circuits. It is completely built in SOI (Silicon On Insulator)
technology, guarantying its functionality from lowest input voltages.

The capability to generate output voltages of 1.8 V to 2.4 V from input
voltages as low as 0.3 V to 0.35 V, coming from a fuel cell or a solar cell,
permits to start DC/DC converter operation with very low input voltages. The
pumped-up charge is stored on a start-up capacitor. When its voltage exceeds
the start voltage threshold, it will boost a step-up DC/DC-converter into
operation. Once started, the DC/DC-converter draws its own supply current
from its stepped-up output voltage. When the VM input of the Start-up IC
monitors an output voltage exceeding the shutdown voltage, it will change to
off state. This will effect in noticeable load reduction to the source and
power saving.

The S-882Z series IC’s are available in SOT-23-5 packages and require
only one external component, the start-up capacitor, to perform their task.

DC/DC converters are also known as switching voltage converters or
regulators. A range of matching switching voltage regulators is offered by
Seiko Instruments with product no. S-8353.
