What are the key features of MAX5035DUPA+?
- Wide input voltage range of 7.5 V to 76 V enables operation from automotive 12 V, industrial 24 V, and telecom 48 V power rails without additional conversion
- Adjustable output from 1.25 V to 13.2 V at up to 1 A covers a broad range of regulated point-of-load voltage requirements
- Dual PWM and PFM control modes automatically optimize efficiency from light-load to full 1 A output, minimizing quiescent current losses
- 8-pin PDIP package simplifies prototyping and evaluation using standard DIP sockets and breadboards without SMT rework equipment
What is MAX5035DUPA+ used for?
The MAX5035DUPA+ is well-suited for industrial and automotive power supply designs requiring a wide 7.5 V to 76 V input stepped down to adjustable regulated voltages between 1.25 V and 13.2 V at up to 1 A. It is commonly used in 24 V industrial control panels, 48 V telecom power systems, and automotive electronics requiring efficient point-of-load conversion. The PDIP package also makes it ideal for rapid prototyping and evaluation of step-down power supply architectures.

Frequently Asked Questions
What input voltage range and output voltages does the MAX5035DUPA+ support?
The MAX5035DUPA+ accepts input voltages from 7.5 V to 76 V and provides an adjustable output from 1.25 V to 13.2 V at up to 1 A. This wide input range makes it compatible with automotive 12 V, industrial 24 V, and telecom 48 V power rails without additional input conversion stages.
How do PWM and PFM modes in MAX5035DUPA+ improve efficiency across varying loads?
At full load up to 1 A, the MAX5035DUPA+ uses PWM for stable regulated output, while at light loads it automatically switches to PFM to minimize quiescent current and maximize efficiency above 80% across a broad load range. This dual-mode approach extends battery or power-supply operating life in applications with highly variable current demand.
Why is the 8-pin PDIP package of MAX5035DUPA+ advantageous for design evaluation?
The 8-pin PDIP package allows the MAX5035DUPA+ to be mounted in standard DIP sockets and solderless breadboards, enabling rapid prototyping of step-down supplies with 7.5 V to 76 V input and 1.25 V to 13.2 V adjustable output. Engineers can freely swap feedback resistors to set output voltage without any SMT soldering equipment, significantly reducing design iteration time.
