MAX5052BEUA

AC DC Converters, Offline Switchers Overview

The MAX5052BEUA is a current-mode PWM controller designed for isolated and nonisolated power supplies. It supports universal offline input voltages, specifically rectified 85VAC to 265VAC. The device features an internal error amplifier with a 1% accurate reference and programmable input startup voltage. It includes digital soft-start and thermal shutdown protection. The switching frequency is fixed at 262kHz ±12%, with a maximum duty-cycle limit of 50%. The component operates within a supply current range of 45µA (typ) startup and 1.4mA (typ) operating current.

AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix 'BEUA' against official Analog Devices documentation to confirm package type and temperature grade. Confirm end-of-life status and availability through authorized distributors. Ensure compatibility with existing board layouts and thermal requirements before procurement.

AC DC Converters, Offline Switchers Selection Notes

Select this component for designs requiring universal AC input ranges or telecom DC inputs. The fixed 262kHz frequency aids in EMI filtering design. Consider the 50% duty cycle limit when designing transformer ratios. Verify that the 8-pin µMAX package fits the mechanical constraints of the target enclosure.

AC DC Converters, Offline Switchers Part Context

The MAX5052 belongs to a family of current-mode PWM controllers from Maxim Integrated, now part of Analog Devices. It is distinct from the MAX5053, which targets lower input voltages. The BEUA suffix typically denotes a specific package variant and industrial temperature range within the MAX5052 product line.

AC DC Converters, Offline Switchers Replacement Considerations

Direct substitutes include the MAX5052AEUA and MAX5052CEUA. Verify pinout and electrical specifications match exactly. Cross-reference with newer Analog Devices power management ICs if obsolescence is a concern.
