XCL230/XCL231 Series

36V, 600mA Inductor Built-in Step-down “micro DC/DC” Converter

■GENERAL DESCRIPTION

ETR28019-002

The XCL230/XCL231 Series is a small (3.0mm×3.0mm, h=1.7mm) 36V, 600mA step-down DC/DC converter with an integrated

control IC and coil. Integrating the coil makes for easier circuit board layout and minimizes malfunction and noise from the

component and wiring layout.

The input voltage range is 3.0 to 36V, the switching frequency is 1.2MHz, and a synchronous rectification circuit is used to achieve

a stable power supply at high efficiency. The XCL230 Series fixes the operation frequency using PWM control to suppress output

ripple voltage.

The XCL231 Series automatically switches between PWM and PFM control to reduce loss by lowering the operation frequency

during low loads to achieve high efficiency across the entire range from low to high loads.

A 0.75V standard voltage supply is built in, and the output voltage can be set to 1.0V to 5.0V using an external resistance.

The soft start time is internally set to 2.0ms, and a time that is longer than the internal soft-start can be freely set depending on the

resistance and capacity connected to the EN/SS pin.

An overcurrent protection function and thermal shutdown function are built in as protective functions to ensure safe use in the

event of a short circuit.
