Overview

The PTH12020WAH is a high-performance, non-isolated point-of-load (PoL) DC-DC converter module capable of delivering up to 18A of output current. It operates from a wide input voltage range of 10.8V to 13.2V and provides an adjustable output voltage from 1.2V to 5.5V using a single external resistor. This module is part of the POLA (Point-of-Load Alliance) standard, ensuring pin-compatibility with other second-source manufacturers.

Why Choose This Part

The module offers excellent efficiency up to 95% and includes high-end features such as Auto-Track sequencing, pre-bias startup, and margin up/down controls for system testing. Its integrated design reduces component count and simplifies PCB layout compared to discrete switching regulator solutions. Built-in protections include non-latching over-current protection and thermal shutdown to ensure long-term reliability.

Applications

High-Speed DSPs and Microprocessors
Provides stable, high-current power rails for advanced digital signal processors and microprocessors that require precise voltage regulation.
Multi-Voltage Digital Systems
Ideal for complex systems requiring multiple power rails with synchronized startup via the Auto-Track sequencing feature.
ITE and Communications Equipment
Used in commercial networking and telecommunications hardware to power bus drivers and high-speed logic from a 12V intermediate bus.

Getting Started

To use the PTH12020WAH, select a single external resistor to set the desired output voltage between 1.2V and 5.5V. Connect the output sense pin directly to the load to compensate for voltage drops across PCB traces. Ensure adequate input and output capacitance is provided as per the datasheet recommendations to minimize ripple and maintain stability during transient loads.
