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
Q

15V 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.
