36V H-Bridge Transformer Driver for Isolated

Supplies

MAX13256

General Description

Benefits and Features

The MAX13256 H-bridge transformer driver provides a

simple solution for making isolated power supplies up to

10W. The device drives a transformer’s primary coil with

up to 300mA of current from a wide 8V to 36V DC supply.

The transformer’s secondary-to-primary winding ratio de-

fines the output voltage, allowing selection of virtually any

isolated output voltage.

● Simple, Flexible Design

• 8V to 36V Supply Range

• Up to 90% Efficiency

• Provides Up to 10W to the Transformer

• Undervoltage Lockout

• 2.5V to 5V Compatible Logic Interface

• Internal or External Clock Source

• Adjustable Overcurrent Threshold

The device features adjustable current limiting, allowing

indirect limiting of secondary-side load currents. The cur-

rent limit of the MAX13256 is set by an external resistor.

A FAULT output asserts when the device detects an

overtemperature or overcurrent condition. In addition, the

device features a low-power mode to reduce the overall

supply current to 0.65mA (typ) when the driver is not in

use.

● Integrated System Protection

• Fault Detection and Indication

• Overcurrent Limiting

• Overtemperature Protection

● Saves Space on Board

• Small 10-Pin TDFN Package (3mm x 3mm)

The device can be operated using the internal oscillator

or driven by an external clock to synchronize multiple

MAX13256 devices and precisely set the switching fre-

quency. Internal circuitry guarantees a fixed 50% duty cy-

cle to prevent DC current flow through the transformer, re-

gardless of which clock source is used.

The device is available in a small 10-pin (3mm x 3mm)

TDFN package and is specified over the -40ºC to +125ºC

automotive temperature range.

Applications

● Power Meters

● Isolated Fieldbus Interfaces

● 24V PLC Supply Isolation

● Medical Equipment

● Motor Controls
