Products (Standard( Products))

Here we introduce examples of ICs used for cell phones implemented as modules using Integrated System in Board.

Thin Form, Miniature 1 or 2 Channel DC/DC Converter Power Supplies

SR Series

These products combine a step-up DC/DC converter, n-channel power MOSFET, and Schottky barrier diode devices in a single module. A switching step-up power supply can easily be implemented with just the addition of external voltage setting resistor, coil, and capacitor components.
