Automotive, 2V to 36V, 2.2MHz, 0.6A/1.2A Buck-Boost Converters with Integrated H-Bridge Architecture

業界初の2MHz車載バックブーストコンバータ、2VコールドクランクからVBATTまでシームレスに動作

製品の詳細

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 MAX20039/40 offer a fixed output voltage of 5V and a programmable range of 4.0V to 15V. See Ordering Information for more details. 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 52uA is available in the 'MAX20040B' and 'MAX20040D' versions of the IC. The ICs can operate with spreadspectrum 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.

説明

MAX20040の評価キット(EVキット)は、ハイサイドおよびローサイドスイッチを内蔵した小型、同期整流バックブーストコンバータファミリのMAX20040用の完全実装および試験済みアプリケーション回路です。各EVキットは+4.5V~+36Vの入力電圧で最大1.2Aを供給するように設計され、無負荷時に使用する自己消費電流はわずか52µAです。安定化後は入力電圧を+2Vに下げることが可能です。PGOOD信号を観察することによって出力電圧品質を監視することができます。
