Categories: DC DC Switching Controllers
Quality Control: Learn More
The Microchip Technology MIC2128YML-T5 is a high-voltage synchronous buck controller designed for efficient step-down power conversion. This device features a wide input voltage range of 4.5V to 75V and supports a maximum duty cycle of 85%. Operating with a switching frequency adjustable from 200kHz to 750kHz, the MIC2128YML-T5 integrates essential control features including Enable, Frequency Control, Power Good, and Soft Start.
Its output is configured as positive, driving a single transistor output. The synchronous rectification capability enhances overall efficiency. Packaged in a 16-QFN (3x3) with an exposed pad for improved thermal performance, this component is suitable for surface mounting. The MIC2128YML-T5 is utilized in applications such as industrial power, automotive systems, and high-power LED lighting where robust and efficient DC-DC conversion is required over a broad temperature range from -40°C to 125°C. It is supplied in tape and reel packaging.
