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.

Features

• Push-Pull Driver for Small Transformers
• Single 3.3V or 5V Supply
• High Primary-side Current Drive
• Low Ripple on Rectified Output
