Overview

The PTH04000WAZ is a non-isolated Point-of-Load (PoL) DC-DC converter module that delivers up to 3A of output current. It operates from a wide input voltage range of 3V to 5.5V and provides an adjustable output voltage from 0.9V to 3.6V using a single external resistor. Part of the POLA (Point-of-Load Alliance) standard, it ensures interoperability and simplified power system design for high-performance processors and logic.

Why Choose This Part

This module features high efficiency up to 92% and includes Auto-Track sequencing, which allows multiple modules to track each other's voltage during power-up and power-down. Integrated protection features like overcurrent, overtemperature, and undervoltage lockout enhance system reliability without requiring external components.

Applications

Distributed Power Architectures
Providing localized voltage regulation from 3.3V or 5V intermediate power buses in telecommunications and networking equipment.
Microprocessor and DSP Power
Supplying precise low-voltage power to core and I/O rails of high-speed digital integrated circuits.
Industrial Instrumentation
Delivering stable, low-noise power for sensitive measurement and control circuits in compact form factors.
