Overview

The TPM6501x/TPM6501xQ is push-pull transformer driver family for isolated power supplies. The TPM6501xQ is qualified for automotive grade AEC-Q100 Grade 1. It is an open-loop center-tapped transformer driver with voltage range from 2.25 V to 5.5 V. It is designed to optimize for EMC and noise performance.

The TPM6501x family is a simple solution for isolated power supply. The device has internal oscillator that generates switching frequency with spreadspectrum on the dual output channels. It supports both 420-kHz option (TPM6501A) and 2.2-MHz option (TPM6501B) for different EMC requirements. The interleaved dual channel low-side outputs will drive the transformer to generate isolated power supply with maximum 1-A switching current.

The TPM6501x device has high efficiency, low 0.25-Ω, and low on-resistance R<sub>ds(ON)</sub> output channels. The device has built-in 1.5-A current limit and over temperature protection features to protect the system from hazardous scenarios.

The TPM6501xQ device is available in SOT23-5 package, and supports wide ambient temperature from -40°C to 125°C.
