MAX25254QAFDF/VY+规格书详情
General Description
The MAX25254/MAX25255 are small, synchronous dual buck converters with integrated high-side and low-side switches. The ICs are designed to deliver up to 8A per channel with input voltages from 3V to 36V while using only 12μA quiescent current at no load. Voltage quality can be monitored by observing the PGOOD signals. The MAX25254/MAX25255 can regulate the output voltage in the dropout region by running at 99 of the duty cycle, making them ideal for automotive and industrial applications.
The MAX25254/MAX25255 offer two fixed output voltages of 5V and 3.3V. Four fixed frequency options allow for small external components and reduced output ripple, and also guarantee no AM interference. The MAX25254/MAX25255 can enter skip mode at light loads with ultra-low quiescent current of 12μA at no load. The MAX25254/MAX25255 can be ordered with spread spectrum enabled for optimum EMI performance.
Two buck converters within the MAX25254D and MAX25255D can be configured for dual-phase operation with up to 16A output load capability. Furthermore, the MAX25254D/MAX25255D and the MAX25254Q/MAX25255Q can be used in parallel to provide 4-phase operation that supports up to 32A (max) output current.
The MAX25254/MAX25255 are available in a small, 4.50mm x 5.75mm, 23-pin FC2QFN package and use very few external components.
