MAX17505SATP+

The MAX17505SATP+ from Analog Devices is a high-efficiency, high-voltage, synchronously rectified step-down converter. It is designed to operate over a wide input voltage range of 4.5V to 60V and can deliver up to 1.7A of output current. The output voltage is adjustable from 0.9V up to 90% of the input voltage.

This device features internal compensation, eliminating the need for external components and simplifying design. It utilizes a peak-current-mode control architecture with a MODE feature that supports PWM, PFM, or DCM control schemes for optimized efficiency across various load conditions. The MAX17505SATP+ is available in a compact 4mm x 4mm TQFN package with an exposed pad, suitable for surface mounting.

Key electrical specifications include a switching frequency range of 200kHz to 2.2MHz, an operating temperature range of -40°C to 125°C (TJ), and a regulation accuracy of ±1.1% over temperature. It also features a programmable soft-start, an output enable/undervoltage lockout pin, and a RESET pin for power-good indication.

Applications for this converter include industrial power supplies, distributed supply regulation, base station power supplies, wall transformer regulation, high-voltage single-board systems, and general-purpose point-of-load applications.
