SN6505x Low-Noise 1-A Transformer Drivers for Isolated Power Supplies

Overview

TopologyPush-Pull Converter symmetrical isolated
Input voltage5 V
Output 15 V

Description

TMDSCNCD280039C is a low-cost evaluation and development board for TI C2000™ MCU series of F28003x devices. It comes with a HSEC180 (180-pin high-speed edge connector) and, as a controlCARD, is ideal for initial evaluation and prototyping. For evaluation of TMDSCNCD280039C, a 180-pin docking station TMDSHSECDOCK is required and can be purchased separately.

Features

  • Push-pull driver for transformers
  • Wide input voltage range: 2.25 V to 5.5 V
  • High output drive: 1 A at 5 V supply
  • Low RON 0.25 Ω max at 4.5 V supply
  • Ultra-low EMI
  • Spread spectrum clocking
  • Precision internal oscillator options: 160 kHz (SN6505A) and 420 kHz (SN6505B)
  • Synchronization of multiple devices with external clock input
  • Slew-rate control
  • 1.7 A Current-limit
  • Low shutdown current: <1 μA
  • Thermal shutdown
  • Wide temperature range: –55°C to 125°C
  • Small 6-Pin SOT23 (DBV) package
  • Soft-start to reduce In-rush current

Typical applications

  • Isolated power supply for CAN, RS-485, RS-422, RS-232, SPI, I2C, low-power LAN, Low-noise isolated USB supplies, Process control, Telecom supplies, Radio supplies, Distributed supplies
  • Medical instruments
