MAX13256
36V H-Bridge Transformer
Driver for Isolated Supplies
Example 3: +24V to Isolated, Regulated ±15V
In Figure 8, the MAX13256 is used with a 1:1.5 center
tapped transformer and a 4-diode bridge rectifier net-
work (see Figure 3C) to supply Q17.1V to a MAX8719
LDO and a 7915 LDO. The circuit produces regulated
Q15V outputs at up to 100mA.
Isolated DAC/ADC Interface for
Industrial Process Control
The MAX13256 provides isolated power for data con-
verters in industrial process control applications (see
Figure 9). The 300mA output current capability allows
for multiple data converters operating across an isola-
tion barrier. The power output capability also supports
circuitry for signal conditioning and multiplexing.
