MAX17543ATP+ Description

Short technical summary and product information.

The MAX17543ATP+ is a high-efficiency, synchronous step-down DC-DC converter from Analog Devices, designed for industrial power supplies and general-purpose point-of-load applications. It operates with an input voltage range of 4.5V to 42V and can deliver an output current of up to 2.5A.

 

This converter utilizes peak current-mode control and offers adjustable output voltages from 0.9V up to 0.9 times the input voltage. The switching frequency is adjustable from 100kHz to 2.2MHz, allowing for flexibility in design and power dissipation optimization. It achieves peak efficiencies greater than 90% and features PFM/DCM modes for enhanced light-load efficiency.

 

The device is housed in a compact 20-TQFN (4mm x 4mm) package, suitable for surface mounting. It includes integrated MOSFETs, internal compensation for any output voltage, and built-in soft-start functionality. The operating temperature range is -40°C to +125°C (junction temperature).

 

Key features include synchronous operation (eliminating the need for a Schottky diode), peak current-limit protection, overtemperature protection, and a programmable EN/UVLO threshold. Its wide input voltage range and robust design make it suitable for adverse industrial environments.
