MAX5974DETE+T Description

Short technical summary and product information.

The Analog Devices MAX5974DETE+T is a peak current-mode control, active-clamped forward PWM controller suitable for DC-DC converters. It features a wide input voltage range of 8.4V to 26V and operates at programmable switching frequencies between 100kHz and 600kHz.

 

Key features include a maximum duty cycle of 80%, synchronization capability, and control functions such as dead time control, enable, frequency control, and soft start. The device is designed for applications like Power-over-Ethernet (PoE) powered devices, IP phones, and wireless access nodes.

 

Packaged in a 16-TQFN (3x3) surface-mount package, the MAX5974DETE+T operates within a temperature range of -40°C to 85°C. Its design incorporates features to enhance supply efficiency, including frequency foldback for light-load conditions and programmable frequency dithering for low-EMI operation.
