Product Overview

The MAX258ATA+T is a 500mA, push-pull transformer driver for isolated power supplies in 8 pin TDFN package. It is a 500mA, push-pull transformer driver designed to provide a simple solution for isolated power supplies. The transformer's secondary to primary winding ratio defines the output voltage allowing selection of virtually any isolated output voltage with galvanic isolation. The device features an integrated oscillator driving a pair of n-channel power switches. Internal circuitry a fixed 50% duty cycle to prevent DC current flow through the transformer. The IC operates with up to 500mA of continuous current and features undervoltage lockout and thermal shutdown. The IC includes a low-current shutdown mode to reduce the overall supply current to less than 5µA (max) when the driver is disabled.
  • Supply voltage range is 3V to 5.5V
  • Operating temperature range from -40°C to 125°C
  • Low RON 300Mohm (max) at 4.5V
  • Up to 90% efficiency
  • 250KHz or 600KHz internal oscillator frequency
  • Supply current is 1.1mA
