MAX759CPD Buck-Boost Switching Regulator IC

Part Overview

The MAX759CPD is a buck-boost switching regulator IC manufactured by Analog Devices Inc./Maxim Integrated, designed for negative adjustable output applications. This component functions as a step-up/step-down converter with a single negative output, capable of delivering 300mA at adjustable voltage levels from 0V to -15V. The device operates across an input voltage range of 4V to 11V with a switching frequency of 185kHz.

The MAX759CPD is classified as an obsolete product. Locating equivalent or substitute components becomes necessary when original stock is depleted or when design requirements mandate compliance with current manufacturing standards and certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX759CPD is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Input voltage range (4V to 11V), output voltage range (0V to -15V), output current (300mA), and switching frequency (185kHz)
• Functional Architecture: Buck-boost topology with negative adjustable output configuration and single output
• Package Compatibility: 14-DIP (0.300", 7.62mm) through-hole mounting
• Operating Conditions: Temperature range 0°C to 70°C

The substitute part MAX759CPD+ maintains identical electrical specifications and package form factor, ensuring direct functional compatibility. The primary distinction lies in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX759CPD+ serves as a direct electrical and mechanical substitute for the MAX759CPD. Both components share identical electrical specifications, functional topology, and package form factor, enabling pin-for-pin replacement in existing circuit designs.

The MAX759CPD+ is classified as an active product with ROHS3 compliance, whereas the original MAX759CPD is obsolete and RoHS non-compliant. Selection of the MAX759CPD+ is appropriate for new designs or production runs requiring compliance with current environmental and manufacturing standards. The MAX759CPD remains suitable for legacy system maintenance or applications where RoHS compliance is not mandated.
