Product Description
Microchip MIC21LV33YML-TR is a highly efficient 5-channel PWM controller with a maximum switching frequency of 1 MHz and an output voltage of up to 36V. Designed in a surface mount 32-pin VQFN package measuring 5mm by 5mm, it is suited for compact power management applications requiring high current delivery, up to 50A.
This controller operates over a broad input voltage range from 4.5V to 36V, with the capability to extend input voltage down to 2V when supplied with an external 5V VDD. Its buck topology offers synchronous step-down conversion, making it suitable for applications demanding precise and efficient voltage regulation.
The MIC21LV33YML-TR features an adjustable output voltage starting from 0.6V with accuracy guaranteed within ±1% over the full operating temperature range of -40°C to 125°C. It also includes adaptive ON-time control architecture paired with Hyper light Load® and phase shedding for enhanced efficiency, particularly under light load conditions.
The device is ideal for various industrial, electronics manufacturing, and power systems control applications, including DC-DC power regulation in embedded systems, server power supplies, telecommunications equipment, and automotive electronics that require robust and precise power management.
Compliant with RoHS standards, this controller ensures environmentally safe manufacturing and disposal. The compact footprint and high current capability allow integration into space-constrained designs without compromising power delivery performance.
