NCV57540DWKR2G onsemi

Here is the English information on the NCV57540DWKR2G chip:

The NCV57540DWKR2G is a synchronous buck-boost DC-DC converter from ON Semiconductor.

Key specifications and features include:

• Input voltage range: 2.5V to 5.5V
• Output voltage range: 2.5V to 5.5V
• Maximum output current: 1A
• Integrated high/low side MOSFETs
• Adjustable soft-start
• Switching frequency up to 1.5MHz
• Protection features such as OVP, OCP, OTP
• Available in small DFN 3x3 package

The NCV57540DWKR2G can provide a regulated output voltage that is either higher or lower than the input voltage. Using integrated MOSFETs, it operates with high efficiency across the entire input/output range.

Soft-start, programmable switching frequency and protection features enable safe operation. The compact DFN package makes it suitable for power delivery in space-constrained applications.

Capable of regulating and converting over the voltage range from 2.5V to 5.5V at up to 1A output, this buck-boost converter provides a versatile solution for applications requiring voltage regulation beyond the capabilities of a standard buck or boost converter.

In summary, the NCV57540DWKR2G is a fully integrated buck-boost converter ideal for applications where the input and output voltages may be at similar levels.
