LM20333MH Description

Short technical summary and product information.

The LM20333MH from Texas Instruments is a current mode synchronous buck regulator designed for efficient power conversion. It operates with an input voltage range of 4.5V to 36V and can deliver up to 3A of output current. The regulator features frequency synchronization, allowing for flexible system design, and provides precise output voltage control with 1.5% feedback voltage accuracy.

This device is suitable for a variety of applications requiring stable power delivery. It includes features such as overcurrent protection, power good output, and prebias startup compatibility. The operating temperature range is from -40°C to 125°C, ensuring reliable performance in demanding environments. The LM20333MH is available in a 20-pin HTSSOP package, designed for efficient heat dissipation and space-saving board layouts.

Key electrical characteristics include a typical quiescent current of 2.3mA and a maximum duty cycle of 80%. The integrated power MOSFETs have an on-resistance of 130 mΩ/110 mΩ, contributing to a peak efficiency of 94% with synchronous rectification. The oscillator synchronization frequency can be adjusted from 250kHz to 1.5MHz. The adjustable output voltage can be set down to 0.8V.
