An ultra compact step-down DC/DC converter that integrates a coil and a control IC in one tiny package. By adding a ceramic capacitor for input/output and a resistor for output voltage setting to external parts, a power supply circuit of up to 500mA can be created.
With an operating voltage range of 3.0V ~ 18.0V and it can support 500mA as an output current with high-efficiency. They use synchronous rectification at an operating frequency of 2.2MHz. The output voltage can be set to a value from 1.0V to 5.0V using external resistors.
The series employs wettable flank plated packaging. Providing a visual indicator of solderability and lowers the inspection time.
