XDL605 Series

36V Operation, 0.6A Inductor Built-in Step-down “micro DC/DC” Converters

The XDL605 series is an ultra compact step-down DC / DC converter that integrates a coil and a control IC in one tiny package. An internal coil simplifies the circuit and enables minimization of noise and other operational trouble due to the circuit wiring. XDL605 series has operating voltage range of 3.0V~36.0V and it can support 0.6A as an output current with high-efficiency. They use synchronous rectification at an operating frequency of 2.2MHz.

0.75V reference voltage source is incorporated in the IC, and the output voltage can be set to a value from 1.0V to 25.0V using external resistors (RFB1, RFB2). They have a fixed internal soft start time which is 2.0ms (TYP.), additionally the time can be extended by using an external resistor and capacitor. The output state can be monitored using the power good function.

Over current protection, short-circuit protection and thermal shutdown are embedded and they secure a safety operation.

The XDL605 series employ the wettable flank plated packaging. This provides a visual indicator of solderability and lowers the inspection time.
