SN6505B - Low-Noise 1-A Transformer Drivers

Download the SN6505B datasheet PDF. This datasheet also covers the SN6505A variant, as both devices belong to the same low-noise 1-a transformer drivers family and are provided as variant models within a single manufacturer datasheet.

General Description

The SN6505x is a low-noise, low-EMI push-pull transformer driver, specifically designed for small form factor, isolated power supplies.

It drives lowprofile, center-tapped transformers from a 2.25 V to 5 V DC power supply.

Key Features

  • 1 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:.
