MAX13253, Transformer Driver

The MAX13253 is a 1A, push-pull, transformer driver designed to provide a simple solution for low-EMI isolated power supplies.

The MAX13253 has an internal oscillator and operates from a single +3.0V to +5.5V supply.

The transformer’s secondary-to-primary winding ratio defines the output voltage, al

MAX13253 Features

* an integrated oscillator driving a pair of n-channel power switches. The driver includes pin-selectable spread-spectrum oscillation and a wellcontrolled slew rate to reduce EMI. The MAX13253 can optionally be driven by an external clock to further manage EMI. Internal circuitry guarantees a fixed 50
