Substitute Part Grouping Explanation

Substitution of the MAX1709ESE is determined by strict equivalence across the following critical parameters:

• Boost topology with positive output configuration
• Adjustable (programmable) output voltage capability
• Single output channel
• Input voltage range: 0.7V to 5V minimum and maximum
• Output voltage range: 2.5V to 5.5V
• Switch current rating: 7.5A
• Switching frequency: 350kHz to 1MHz
• Absence of synchronous rectifier
• Operating temperature range: -40°C to 85°C
• 16-SOIC surface mount package with 0.154" (3.90mm) width
• Base product number: MAX1709

The MAX1709ESE+ meets all electrical and mechanical substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MAX1709ESE+ is the direct equivalent substitute for the MAX1709ESE. Both parts share identical electrical specifications and mechanical packaging. The MAX1709ESE+ is currently in active production status, whereas the MAX1709ESE is obsolete.
