Introduction

AI Translation

The MAX20039/MAX20040 ICs are a small, synchronous buck-boost converter family with integrated high-side and low-side switches. The MAX20040 is designed to deliver up to 1.2A with input voltages from 2V to 36V while using only 52μA quiescent current at no load. The ICs provide an accurate output voltage of ±2%. Voltage quality can be monitored by observing the PGOOD signal. The MAX20039/MAX20040 offer a fixed output voltage of 5V and a programmable range of 4.0V to 15V. Frequency is adjustable from 220kHz to 2.2MHz, which allows for small external components, reduced output ripple, and guarantees no AM interference. Skip mode with low quiescent current of 52μA is available in the MAX20040B and MAX20040D versions of the IC. The ICs can operate with spread-spectrum frequency modulation designed to minimize EMI-radiated emissions due to the modulation frequency. The MAX20039/MAX20040 are available in a small, 4mm x 4mm, 20-pin, side-wettable TQFN package and use very few external components.
