Texas Instruments SN6501 | Demoboard SN6501-MULXFMR-EVM
SN6501 Transformer Driver for Isolated Power Supplies Evaluation Module
Overview
| Topology | Push-Pull Converter symmetrical isolated |
| Input voltage | 3.3 V |
| Output 1 | 3.3 V |
| Output 2 | 5 V |
Description
The SN6501-Multi-Xfmr EVM is configured with five independent circuits providing options to operate using either a +3.3Vdc or +5.0Vdc input and provides one of five isolated 3.3Vdc +5.0Vdc outputs. Two of the circuits include LDO's to regulate the output. The five configurations include 3Vdc-to-3Vdc with no LDO, 5Vdc-to-5Vdc with no LDO, 3Vdc-to-5Vdc with no LDO, 3Vdc-to-5Vdc with and LDO, and a 3Vdc/5Vdc-to-3Vdc/5Vdc with a selectable LDO output.
