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.
