STMicroelectronics, a global semiconductor leader serving customers across the spectrum of electronics applications, offers a simple and efficient solution for powering low-voltage loads such as smart meters, home appliances, and industrial applications.

ST announced on the 27th that it has launched the new DCP3601 ultra-small monolithic buck converter.

The DCP3601 supports an input voltage range from 3.3 V to 36 V and an output of 1 A.

The design includes built-in power switches and compensation circuits, allowing the circuit to be completed with only six external components: an inductor, bootstrap, filter capacitor, and feedback resistor to set the output voltage. This allows high conversion efficiency to be achieved while reducing the bill of materials (BOM).

This converter ensures high efficiency across all operating conditions and load ranges through synchronous rectification and a fixed switching frequency of 1MHz.

For example, it achieves up to 91% efficiency at 600mA with 12V input and 5V output.

It also provides flexibility by offering forced PWM operation to support noise-sensitive applications or pulse-skipping options for minimum power consumption at light loads.

Designers can quickly get started with new projects using the dedicated evaluation board, STEVAL-3601CV1.

The board is ready to drive out of the box with screw terminals and headers, and its small footprint allows for efficient circuit design.
ST will expand its family of new buck converters throughout the year, starting with the DCP3601.

The DCP3601 is backed by ST’s 10-year long-term supply program, ensuring long-term parts availability and support, and is offered in a 3mm x 1.6mm SOT23 6-lead package. The single-chip buck converter is priced at $0.48 for orders of 1000 pieces.
