MAX17503ATP+ Description

Short technical summary and product information.

The MAX17503ATP+ is a high-efficiency, high-voltage, synchronously rectified step-down converter IC from Analog Devices, part of the Himalaya series. It operates over a wide 4.5V to 60V input voltage range and can deliver up to 2.5A of output current. The output voltage is adjustable from 0.9V up to 90% of the input voltage, with a maximum of 54V.

 

This device features internal compensation, eliminating the need for external components and simplifying design. It offers adjustable switching frequencies from 100kHz to 2.2MHz, with options for synchronization. The MAX17503ATP+ supports peak-current-mode control with selectable PWM, PFM, or DCM modes for optimizing efficiency across various load conditions. It includes a programmable soft-start feature to reduce inrush current and an EN/UVLO pin for input voltage lockout control. A RESET pin provides a power-good signal.

 

The MAX17503ATP+ is available in a compact 4mm x 4mm TQFN-EP package with an exposed pad, suitable for surface mounting. Its operating temperature range is -40°C to +125°C (TJ). Applications include industrial power supplies, distributed supply regulation, and base station power supplies.
