Voltage Regulators - DC DC Switching Regulators datasheet and documents for MAX5033AUPA+

MAX5033AUPA+

Voltage Regulators - DC DC Switching Regulators Overview

The MAX5033AUPA+ is a high-efficiency, fixed-output step-down DC-DC converter manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates as a buck topology switching regulator with a single positive output configured at 3.3 V and a maximum output current of 500 mA. The device accepts an input voltage range from 7.5 V to 76 V and functions at a fixed switching frequency of 125 kHz. It does not include synchronous rectification. The component is housed in an 8-pin PDIP package designed for through-hole mounting. It supports operation within a temperature range of 0°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

High-voltage input capability up to 76 V for direct bus regulation
Fixed 3.3 V output with 500 mA current capacity
Integrated 125 kHz switching frequency for compact passive design
Through-hole PDIP-8 packaging for standard board assembly

Voltage Regulators - DC DC Switching Regulators Applications

Industrial control systems requiring isolated or non-isolated power stages
Automotive electronics operating on 12V or 24V nominal buses
Telecommunications infrastructure power distribution
General-purpose point-of-load regulation for mid-range voltage rails

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm RoHS compliance documentation matches specific manufacturing lot requirements. Check for obsolescence notices from Analog Devices regarding final purchase dates. Ensure supply chain sources provide valid traceability records for quality assurance purposes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 3.3 V output is required from a high-voltage source without needing adjustable regulation. Consider the through-hole package constraint against available PCB layout space. Evaluate thermal performance at full load given the lack of active cooling specifications. Compare against surface-mount alternatives if board density is a primary design driver.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the MAX5033 family of MAXPower step-down converters. It shares core electrical characteristics with variants like the MAX5033DUSA+ (adjustable) and MAX5033BASA+T (5V fixed), differing primarily in output voltage configuration and physical package type. The A suffix denotes the specific 3.3 V fixed output version.
